xterm


SYNOPSIS
       xterm [-toolkitoption ...] [-option ...] [shell]

DESCRIPTION
       The  xterm  program is a terminal emulator for the X Window System.  It
       provides DEC VT102/VT220 and selected features from higher-level termi-
       nals  such  as  VT320/VT420/VT520  (VTxxx).  It also provides Tektronix
       4014 emulation for programs that cannot use the window system directly.
       If the underlying operating system supports terminal resizing capabili-
       ties (for example, the SIGWINCH signal in systems derived from 4.3bsd),
       xterm  will use the facilities to notify programs running in the window
       whenever it is resized.

       The VTxxx and Tektronix 4014 terminals each have their  own  window  so
       that  you can edit text in one and look at graphics in the other at the
       same time.  To maintain the correct aspect ratio  (height/width),  Tek-
       tronix  graphics  will  be  restricted to the largest box with a 4014's
       aspect ratio that will fit in the window.  This box is located  in  the
       upper left area of the window.

       Although both windows may be displayed at the same time, one of them is
       considered the "active" window for receiving keyboard input and  termi-
       nal  output.   This  is  the window that contains the text cursor.  The
       active window can be chosen through escape sequences, the "VT  Options"
       menu  in  the VTxxx window, and the "Tek Options" menu in the 4014 win-
       dow.

EMULATIONS
       The VT102 emulation is fairly complete, but does  not  support  autore-
       peat.   Double-size  characters  are  displayed  properly  if your font
       server supports scalable fonts.  The VT220 emulation does  not  support
       soft  fonts,  it  is  otherwise complete.  Termcap(5) entries that work
       with xterm  include  an  optional  platform-specific  entry  ("xterm"),
       "xterm",  "vt102",  "vt100",  "ansi"  and  "dumb".  xterm automatically
       searches the termcap file in this order for these entries and then sets
       the  "TERM"  and the "TERMCAP" environment variables.  You may also use
       "vt220",  but must set the terminal emulation level with the  decTermi-
       nalID  resource.   (The  "TERMCAP"  environment  variable is not set if
       xterm is linked against a terminfo library, since the requisite  infor-
       mation is not provided by the termcap emulation of terminfo libraries).

       Many  of  the special xterm features may be modified under program con-
       trol through a set of escape  sequences  different  from  the  standard
       VT102 escape sequences.  (See the Xterm Control Sequences document.)

       The  Tektronix  4014 emulation is also fairly good.  It supports 12-bit
       graphics addressing, scaled to the window size.   Four  different  font
       sizes and five different lines types are supported.  There is no write-
       through or defocused mode support.  The  Tektronix  text  and  graphics
       commands  are recorded internally by xterm and may be written to a file
       by sending the COPY escape sequence (or through the Tektronix menu; see
       below).   The name of the file will be "COPYyyyy-MM-dd.hh:mm:ss", where
       yyyy, MM, dd, hh, mm and ss are the year, month, day, hour, minute  and
       cursor is highlighted no matter where the pointer is.

       In VT102 mode, there are escape sequences to activate and deactivate an
       alternate  screen buffer, which is the same size as the display area of
       the window.  When activated, the current screen is saved  and  replaced
       with the alternate screen.  Saving of lines scrolled off the top of the
       window is disabled until the normal screen is restored.  The termcap(5)
       entry  for xterm allows the visual editor vi(1) to switch to the alter-
       nate screen for editing and to restore the screen  on  exit.   A  popup
       menu  entry  makes it simple to switch between the normal and alternate
       screens for cut and paste.

       In either VT102 or Tektronix mode, there are escape sequences to change
       the name of the windows.  Additionally, in VT102 mode, xterm implements
       the window-manipulation control sequences from dtterm, such as resizing
       the window, setting its location on the screen.

       Xterm allows character-based applications to receive mouse events (cur-
       rently button-press and release events, and  button-motion  events)  as
       keyboard control sequences.  See Xterm Control Sequences for details.

OPTIONS
       The xterm terminal emulator accepts the standard X Toolkit command line
       options as well as many application-specific options.   If  the  option
       begins  with  a  `+'  instead  of  a `-', the option is restored to its
       default value.  The -version and -help options are interpreted even  if
       xterm  cannot open the display, and are useful for testing and configu-
       ration scripts.  Along with  -class,  they  are  checked  before  other
       options.

       -version
               This  causes  xterm  to  print a version number to the standard
               output, and then exit.

       -help   This causes xterm to print out a verbose message describing its
               options,  one per line.  The message is written to the standard
               output.  After printing the message, xterm exits.  Xterm gener-
               ates this message, sorting it and noting whether a "-option" or
               a "+option" turns the feature on or off,  since  some  features
               historically  have  been  one  or the other.  Xterm generates a
               concise help  message  (multiple  options  per  line)  when  an
               unknown option is used, e.g.,

                   xterm -z

       If  the  logic  for a particular option such as logging is not compiled
       into xterm, the help text for that option also is not displayed by  the
       -help option.

       One parameter (after all options) may be given.  That overrides xterm's
       built-in choice of shell program.   Normally  xterm  checks  the  SHELL
       variable.   If  that  is  not set, xterm tries to use the shell program
       specified in the password  file.   If  that  is  not  set,  xterm  uses
       /bin/sh.  If the parameter is not a relative path, i.e., beginning with
       -ah     This option indicates that xterm should  always  highlight  the
               text cursor.  By default, xterm will display a hollow text cur-
               sor whenever the focus is lost or the pointer leaves  the  win-
               dow.

       +ah     This  option  indicates  that xterm should do text cursor high-
               lighting based on focus.

       -ai     This option disables active icon support if  that  feature  was
               compiled  into  xterm.  This is equivalent to setting the vt100
               resource activeIcon to "false".

       +ai     This option enables active icon support  if  that  feature  was
               compiled  into  xterm.  This is equivalent to setting the vt100
               resource activeIcon to "true".

       -aw     This option indicates that auto-wraparound should  be  allowed.
               This  allows  the cursor to automatically wrap to the beginning
               of the next line when it is at the rightmost position of a line
               and text is output.

       +aw     This  option  indicates  that  auto-wraparound  should  not  be
               allowed.

       -b number
               This option specifies the size of the inner  border  (the  dis-
               tance  between  the outer edge of the characters and the window
               border) in pixels.  That is the vt100 internalBorder  resource.
               The default is "2".

       +bc     turn  off text cursor blinking.  This overrides the cursorBlink
               resource.

       -bc     turn on text cursor blinking.  This overrides  the  cursorBlink
               resource.

       -bcf milliseconds
               set the amount of time text cursor is off when blinking via the
               cursorOffTime resource.

       -bcn milliseconds
               set the amount of time text cursor is on when blinking via  the
               cursorOffTime resource.

       -bdc    Set  the  vt100  resource colorBDMode to "false", disabling the
               display of characters with bold attribute as color

       +bdc    Set the vt100 resource colorBDMode to "true", enabling the dis-
               play  of  characters  with  bold attribute as color rather than
               bold

       -cb     Set the vt100 resource cutToBeginningOfLine to "false".

       +cb     Set the vt100 resource cutToBeginningOfLine to "true".
               of  2.  It also should be turned on when you specify a TrueType
               CJK double-width (bi-width/monospace) font either with  -fa  at
               the command line or faceName resource.  The default is "false"

       +cjk_width
               Reset the cjkWidth resource.

       -class string
               This  option  allows  you  to  override xterm's resource class.
               Normally it is "XTerm", but can be set to another class such as
               "UXTerm" to override selected resources.

       -cm     This  option  disables  recognition of ANSI color-change escape
               sequences.  It sets the colorMode resource to "false".

       +cm     This option enables recognition  of  ANSI  color-change  escape
               sequences.  This is the same as the vt100 resource colorMode.

       -cn     This  option indicates that newlines should not be cut in line-
               mode selections.  It sets the cutNewline resource to "false".

       +cn     This option indicates that newlines should be cut in  line-mode
               selections.  It sets the cutNewline resource to "true".

       -cr color
               This  option  specifies  the color to use for text cursor.  The
               default is to use the same foreground color that  is  used  for
               text.  It sets the cursorColor resource according to the param-
               eter.

       -cu     This option indicates that xterm should work around  a  bug  in
               the more(1) program that causes it to incorrectly display lines
               that are exactly the width of the window and are followed by  a
               line beginning with a tab (the leading tabs are not displayed).
               This option is so named because it was originally thought to be
               a bug in the curses(3x) cursor motion package.

       +cu     This  option  indicates  that  xterm should not work around the
               more(1) bug mentioned above.

       -dc     This option disables the escape sequence to change dynamic col-
               ors:  the vt100 foreground and background colors, its text cur-
               sor color, the pointer cursor foreground and background colors,
               the  Tektronix  emulator  foreground and background colors, its
               text cursor color and highlight color.   The  option  sets  the
               dynamicColors option to "false".

       +dc     This  option enables the escape sequence to change dynamic col-
               ors.  The option sets the dynamicColors option to "true".

       -e program [ arguments ... ]
               This option specifies the program (and its command  line  argu-
               ments)  to be run in the xterm window.  It also sets the window
               title and icon name to be the basename  of  the  program  being

               This font must be the same height and width as the normal font,
               otherwise  it  is  ignored.   If only one of the normal or bold
               fonts is specified, it will be used as the normal font and  the
               bold font will be produced by overstriking this font.

               See   also   the  discussion  of  boldMode  and  alwaysBoldMode
               resources.

       -fa pattern
               This option sets  the  pattern  for  fonts  selected  from  the
               FreeType  library if support for that library was compiled into
               xterm.  This corresponds to the faceName resource.  When a  CJK
               double-width  font  is  specified, you also need to turn on the
               cjkWidth resource.

               See also the renderFont resource, which combines with  this  to
               determine whether FreeType fonts are initially active.

       -fbb    This option indicates that xterm should compare normal and bold
               fonts bounding boxes to ensure they are  compatible.   It  sets
               the freeBoldBox resource to "false".

       +fbb    This  option indicates that xterm should not compare normal and
               bold fonts bounding boxes to ensure they  are  compatible.   It
               sets the freeBoldBox resource to "true".

       -fbx    This  option  indicates  that  xterm should not assume that the
               normal and bold fonts have VT100 line-drawing  characters.   If
               any  are  missing, xterm will draw the characters directly.  It
               sets the forceBoxChars resource to "false".

       +fbx    This option indicates that xterm should assume that the  normal
               and bold fonts have VT100 line-drawing characters.  It sets the
               forceBoxChars resource to "true".

       -fd pattern
               This option sets the pattern for  double-width  fonts  selected
               from  the FreeType library if support for that library was com-
               piled into xterm.  This corresponds to  the  faceNameDoublesize
               resource.

       -fi font
               This  option sets the font for active icons if that feature was
               compiled into xterm.

               See also the discussion of the iconFont resource.

       -fs size
               This option sets the pointsize  for  fonts  selected  from  the
               FreeType  library if support for that library was compiled into
               xterm.  This corresponds to the faceSize resource.

       -fullscreen
               as the font that will be used to draw normal text.  If no  dou-
               ble-width  font  is found, it will improvise, by stretching the
               normal font.  This corresponds to the wideFont resource.

       -fwb font
               This option specifies the font to be used for  displaying  bold
               wide  text.  By default, it will attempt to use a font twice as
               wide as the font that will be used to draw bold  text.   If  no
               double-width  font  is  found, it will improvise, by stretching
               the bold font.  This corresponds to the wideBoldFont resource.

       -fx font
               This option specifies the font to be used  for  displaying  the
               preedit string in the "OverTheSpot" input method.

               See also the discussion of the ximFont resource.

       -hc color
               (see -selbg).

       -hf     This  option indicates that HP Function Key escape codes should
               be generated for function keys.   It  sets  the  hpFunctionKeys
               resource to "true".

       +hf     This  option indicates that HP Function Key escape codes should
               not be generated for function keys.  It sets the hpFunctionKeys
               resource to "false".

       -hm     Tells  xterm  to  use  highlightTextColor and highlightColor to
               override the reversed foreground/background colors in a  selec-
               tion.  It sets the highlightColorMode resource to "true".

       +hm     Tells xterm not to use highlightTextColor and highlightColor to
               override the reversed foreground/background colors in a  selec-
               tion.  It sets the highlightColorMode resource to "false".

       -hold   Turn  on  the  hold  resource, i.e., xterm will not immediately
               destroy its window when the shell command completes.   It  will
               wait  until you use the window manager to destroy/kill the win-
               dow, or if you use the menu entries that send a  signal,  e.g.,
               HUP or KILL.

       +hold   Turn  off  the  hold  resource,  i.e.,  xterm  will immediately
               destroy its window when the shell command completes.

       -ie     Turn on the ptyInitialErase resource, i.e., use the pseudo-ter-
               minal's sense of the stty erase value.

       +ie     Turn off the ptyInitialErase resource, i.e., set the stty erase
               value using the kb string from the termcap entry  as  a  refer-
               ence, if available.

       -im     Turn  on the useInsertMode resource, which forces use of insert
               mode by adding appropriate entries to the  TERMCAP  environment
               used to demonstrate the feature.  When using Gtk,  there  is  a
               limitation   of   that  toolkit  which  requires  that  xterm's
               allowSendEvents resource is enabled.

       -j      This option indicates that xterm should do jump scrolling.   It
               corresponds  to  the  jumpScroll  resource.   Normally, text is
               scrolled one line at a time; this option allows xterm  to  move
               multiple  lines  at  a  time  so  that  it does not fall as far
               behind.  Its use is strongly recommended since it  makes  xterm
               much  faster  when scanning through large amounts of text.  The
               VT100 escape sequences for enabling and disabling smooth scroll
               as  well as the "VT Options" menu can be used to turn this fea-
               ture on or off.

       +j      This option indicates that xterm should not do jump scrolling.

       -k8     This  option  sets   the   allowC1Printable   resource.    When
               allowC1Printable is set, xterm overrides the mapping of C1 con-
               trol characters (code 128-159) to treat them as printable.

       +k8     This option resets the allowC1Printable resource.

       -kt keyboardtype
               This option sets the keyboardType  resource.   Possible  values
               include:  "unknown",  "default", "hp", "sco", "sun", "tcap" and
               "vt220".

               The value "unknown", causes the corresponding  resource  to  be
               ignored.

               The   value  "default",  suppresses  the  associated  resources
               hpFunctionKeys, scoFunctionKeys, sunFunctionKeys, tcapFunction-
               Keys and sunKeyboard, using the Sun/PC keyboard layout.

       -l      Turn  logging  on.   Normally  logging is not supported, due to
               security concerns.  Some versions of  xterm  may  have  logging
               enabled.   The  logfile  is written to the directory from which
               xterm is invoked.  The filename is generated, of the form

                    XtermLog.XXXXXX

               or

                    Xterm.log.hostname.yyyy.mm.dd.hh.mm.ss.XXXXXX

               depending on how xterm was built.

       +l      Turn logging off.

       -lc     Turn on support of various encodings according  to  the  users'
               locale  setting,  i.e.,  LC_ALL,  LC_CTYPE, or LANG environment
               variables.  This is achieved by turning on UTF-8  mode  and  by
               invoking  luit  for  conversion  between  locale  encodings and
               UTF-8.  (luit is not invoked in UTF-8  locales.)   This  corre-

       -lcc path
               File  name  for the encoding converter from/to locale encodings
               and UTF-8 which is used with -lc  option  or  locale  resource.
               This corresponds to the localeFilter resource.

       -leftbar
               Force  scrollbar to the left side of VT100 screen.  This is the
               default, unless you have set the rightScrollBar resource.

       -lf filename
               Specify the log-filename.  See the -l option.

       -ls     This option indicates that the shell that  is  started  in  the
               xterm  window  will be a login shell (i.e., the first character
               of argv[0] will be a dash, indicating  to  the  shell  that  it
               should read the user's .login or .profile).

               The  -ls  flag and the loginShell resource are ignored if -e is
               also given, because xterm does not know how to make  the  shell
               start  the  given  command  after whatever it does when it is a
               login shell - the user's shell of choice need not be  a  Bourne
               shell  after all.  Also, xterm -e is supposed to provide a con-
               sistent functionality for other applications that need to start
               text-mode  programs  in  a  window,  and if loginShell were not
               ignored, the result of ~/.profile might interfere with that.

               If you do want the effect of -ls and -e simultaneously, you may
               get away with something like

                   xterm -e /bin/bash -l -c "my command here"

               Finally,  -ls  is  not completely ignored, because xterm -ls -e
               does write a /var/log/wtmp entry  (if  configured  to  do  so),
               whereas xterm -e does not.

       -maximized
               This  option indicates that xterm should ask the window manager
               to maximize its layout on startup.   This  corresponds  to  the
               maximized resource.

               Maximizing  is not the reverse of iconifying; it is possible to
               do both with certain window managers.

       +maximized
               This option indicates that xterm should ask the window  manager
               to not maximize its layout on startup.

       +ls     This option indicates that the shell that is started should not
               be a login shell (i.e., it will be a normal "subshell").

       -mb     This option indicates that xterm should ring a margin bell when
               the user types near the right end of a line.

       +mb     This option indicates that margin bell should not be rung.
               Set the mkWidth resource to "true".  This  makes  xterm  use  a
               built-in  version of the wide-character width calculation.  The
               default is "false"

       +mk_width
               Reset the mkWidth resource.

       -ms color
               This option specifies the color to be used for the pointer cur-
               sor.   The  default  is to use the foreground color.  This sets
               the pointerColor resource.

       -nb number
               This option specifies the number of characters from  the  right
               end  of a line at which the margin bell, if enabled, will ring.
               The default is "10".

       -nul    This option disables the display of underlining.

       +nul    This option enables the display of underlining.

       -pc     This option enables the PC-style use of bold colors (see  bold-
               Colors resource).

       +pc     This option disables the PC-style use of bold colors.

       -pob    This option indicates that the window should be raised whenever
               a Control-G is received.

       +pob    This option indicates that the  window  should  not  be  raised
               whenever a Control-G is received.

       -rightbar
               Force scrollbar to the right side of VT100 screen.

       -rvc    This  option  disables  the  display of characters with reverse
               attribute as color.

       +rvc    This option enables the  display  of  characters  with  reverse
               attribute as color.

       -rw     This   option   indicates  that  reverse-wraparound  should  be
               allowed.  This allows the cursor to back up from  the  leftmost
               column  of  one  line  to  the rightmost column of the previous
               line.  This is very useful for editing long shell command lines
               and  is  encouraged.  This option can be turned on and off from
               the "VT Options" menu.

       +rw     This option indicates that  reverse-wraparound  should  not  be
               allowed.

       -s      This  option  indicates  that  xterm may scroll asynchronously,
               meaning that the screen does not have to be kept completely  up
               to  date while scrolling.  This allows xterm to run faster when

       +samename
               Always send title and icon name change requests.

       -sb     This  option  indicates  that  some  number  of  lines that are
               scrolled off the top of the window should be saved and  that  a
               scrollbar  should  be  displayed  so  that  those  lines can be
               viewed.  This option may be turned on  and  off  from  the  "VT
               Options" menu.

       +sb     This option indicates that a scrollbar should not be displayed.

       -selbg color
               This  option  specifies  the color to use for the background of
               selected text.  If not specified, reverse video is  used.   See
               the discussion of the highlightColor resource.

       -selfg color
               This  option  specifies the color to use for selected text.  If
               not specified, reverse video is used.  See  the  discussion  of
               the highlightTextColor resource.

       -sf     This option indicates that Sun Function Key escape codes should
               be generated for function keys.

       +sf     This option indicates that the standard escape codes should  be
               generated for function keys.

       -sh number
               scale  line-height values by the given number.  See the discus-
               sion of the scaleHeight resource.

       -si     This option indicates that output to a window should not  auto-
               matically  reposition the screen to the bottom of the scrolling
               region.  This option can be turned on  and  off  from  the  "VT
               Options" menu.

       +si     This  option  indicates that output to a window should cause it
               to scroll to the bottom.

       -sk     This option indicates that  pressing  a  key  while  using  the
               scrollbar  to  review  previous  lines of text should cause the
               window to be repositioned automatically in the normal  position
               at the bottom of the scroll region.

       +sk     This  option  indicates  that  pressing  a  key while using the
               scrollbar should not cause the window to be repositioned.

       -sl number
               This option specifies the number of lines  to  save  that  have
               been  scrolled  off the top of the screen.  This corresponds to
               the saveLines resource.  The default is "64".

       -sm     This option, corresponding to the  sessionMgt  resource,  indi-
               cates that xterm should set up session manager callbacks.
               mode, rather than in VT102 mode.   Switching  between  the  two
               windows  is done using the "Options" menus.  Termcap(5) entries
               that  work  with   xterm   "tek4014",   "tek4015",   "tek4012",
               "tek4013", "tek4010", and "dumb".  xterm automatically searches
               the termcap file in this order for these entries and then  sets
               the "TERM" and the "TERMCAP" environment variables.

       +t      This option indicates that xterm should start in VT102 mode.

       -tb     This  option,  corresponding to the toolBar resource, indicates
               that xterm should display a toolbar (or menubar) at the top  of
               its window.  The buttons in the toolbar correspond to the popup
               menus, e.g., control/left/mouse for "Main Options".

       +tb     This option indicates that xterm should not set up a toolbar.

       -ti term_id
               Specify the name used by xterm to select the  correct  response
               to terminal ID queries.  It also specifies the emulation level,
               used to  determine  the  type  of  response  to  a  DA  control
               sequence.   Valid  values  include  vt52,  vt100, vt101, vt102,
               vt220, and vt240  (the  "vt"  is  optional).   The  default  is
               "vt420".   The  term_id  argument  specifies the terminal ID to
               use.  (This is the same as the decTerminalID resource).

       -tm string
               This option specifies a series  of  terminal  setting  keywords
               followed  by the characters that should be bound to those func-
               tions, similar to the stty program.   The  keywords  and  their
               values are described in detail in the ttyModes resource.

       -tn name
               This  option  specifies the name of the terminal type to be set
               in the  TERM  environment  variable.   It  corresponds  to  the
               termName resource.  This terminal type must exist in the termi-
               nal database (termcap or terminfo, depending on  how  xterm  is
               built)  and  should  have li# and co# entries.  If the terminal
               type is not  found,  xterm  uses  the  built-in  list  "xterm",
               "vt102", etc.

       -u8     This  option  sets  the utf8 resource.  When utf8 is set, xterm
               interprets incoming data as UTF-8.   This  sets  the  wideChars
               resource  as  a  side-effect,  but  the  UTF-8 mode set by this
               option prevents it from being turned off.  If you must turn  it
               on and off, use the wideChars resource.

               This option and the utf8 resource are overridden by the -lc and
               -en options and locale resource.  That is, if  xterm  has  been
               compiled  to  support  luit,  and  the  locale  resource is not
               "false" this option is ignored.  We  recommend  using  the  -lc
               option  or  the  "locale: true"  resource in UTF-8 locales when
               your operating system supports locale, or -en UTF-8  option  or
               the  "locale: UTF-8"  resource  when your operating system does
               not support locale.

       -ulit   This option, corresponding to the italicULMode  resource,  dis-
               ables  the  display  of  characters with underline attribute as
               italics rather than with underlining.

       +ulit   This  option,  corresponding  to  the  italicULMode   resource,
               enables  the  display of characters with underline attribute as
               italics rather than with underlining.

       -ut     This option indicates that xterm should not write a record into
               the the system utmp log file.

       +ut     This option indicates that xterm should write a record into the
               system utmp log file.

       -vb     This option indicates that a visual bell is preferred  over  an
               audible  one.   Instead of ringing the terminal bell whenever a
               Control-G is received, the window will be flashed.

       +vb     This option indicates that a visual bell should not be used.

       -wc     This option sets the wideChars  resource.   When  wideChars  is
               set, xterm maintains internal structures for 16-bit characters.
               If you do not set this resource to "true",  xterm  will  ignore
               the  escape  sequence  which  turns UTF-8 mode on and off.  The
               default is "false".

       +wc     This option resets the wideChars resource.

       -wf     This option indicates that xterm should wait for the window  to
               be mapped the first time before starting the subprocess so that
               the initial terminal size settings  and  environment  variables
               are  correct.   It is the application's responsibility to catch
               subsequent terminal size changes.

       +wf     This option indicates that xterm should not wait before  start-
               ing the subprocess.

       -ziconbeep percent
               Same  as  zIconBeep  resource.   If percent is non-zero, xterms
               that produce output while iconified will cause an  XBell  sound
               at  the  given  volume  and  have "***" prepended to their icon
               titles.  Most window managers will detect this  change  immedi-
               ately,  showing  you  which  window has the output.  (A similar
               feature was in x10 xterm.)

       -C      This option indicates that this window should  receive  console
               output.   This is not supported on all systems.  To obtain con-
               sole output, you must be the owner of the console  device,  and
               you  must  have  read  and write permission for it.  If you are
               running X under xdm on the console screen you may need to  have
               the  session  startup  and reset programs explicitly change the
               ownership of the console device in order to get this option  to
               work.

                   -S/dev/pts/123/45
                   -S123/45
                   -Sab34

               Note that xterm does not close any file descriptor which it did
               not open for its own use.  It is possible (though probably  not
               portable)  to  have  an  application  which passes an open file
               descriptor down to xterm past  the  initialization  or  the  -S
               option to a process running in the xterm.

   OLD OPTIONS
       The  following  command  line  arguments are provided for compatibility
       with older versions.  They may not be supported in the next release  as
       the X Toolkit provides standard options that accomplish the same task.

       %geom   This  option  specifies  the preferred size and position of the
               Tektronix window.  It is shorthand for specifying the  "*tekGe-
               ometry" resource.

       #geom   This  option  specifies the preferred position of the icon win-
               dow.   It  is  shorthand  for  specifying  the  "*iconGeometry"
               resource.

       -T string
               This  option  specifies  the  title for xterm's windows.  It is
               equivalent to -title.

       -n string
               This option specifies the icon name for xterm's windows.  It is
               shorthand  for  specifying the "*iconName" resource.  Note that
               this is not the same as the toolkit option -name  (see  below).
               The default icon name is the application name.

               If  no  suitable  icon  is  found, xterm provides a compiled-in
               pixmap.

       -r      This option indicates that reverse video should be simulated by
               swapping  the  foreground and background colors.  It is equiva-
               lent to -rv.

       -w number
               This option specifies the width in pixels of  the  border  sur-
               rounding the window.  It is equivalent to -borderwidth or -bw.

   X TOOLKIT OPTIONS
       The  following  standard  X Toolkit command line arguments are commonly
       used with xterm:

       -bd color
               This option specifies the color to use for the  border  of  the
               window.  The corresponding resource name is borderColor.  xterm
               uses the X Toolkit default, which is "XtDefaultForeground".

               dow frame.  Most window managers do not use  this  information.
               See the -b option, which controls the inner border of the xterm
               window.

       -display display
               This option specifies the X server to contact; see X(7).

       -fg color
               This option specifies the color to  use  for  displaying  text.
               The  corresponding resource name is foreground.  The default is
               "XtDefaultForeground".

       -fn font
               This option specifies the font to be used for displaying normal
               text.   The  corresponding resource name is font.  The resource
               value default is fixed.

       -font font
               This is the same as -fn.

       -geometry geometry
               This option specifies the preferred size and  position  of  the
               VT102 window; see X(7).

       -iconic This  option indicates that xterm should ask the window manager
               to start it as an icon rather than as the normal  window.   The
               corresponding resource name is iconic.

       -name name
               This   option   specifies  the  application  name  under  which
               resources are to be obtained,  rather  than  the  default  exe-
               cutable  file name.  Name should not contain "." or "*" charac-
               ters.

       -rv     This option indicates that reverse video should be simulated by
               swapping the foreground and background colors.  The correspond-
               ing resource name is reverseVideo.

       +rv     Disable the simulation of reverse video by swapping  foreground
               and background colors.

       -title string
               This  option  specifies  the  window title string, which may be
               displayed by window managers  if  the  user  so  chooses.   The
               default  title  is  the  command  line  specified  after the -e
               option, if any, otherwise the application name.

       -xrm resourcestring
               This option specifies a resource string to be  used.   This  is
               especially  useful for setting resources that do not have sepa-
               rate command line options.

RESOURCES
       The program understands all of the core X Toolkit  resource  names  and
               keyword (ignoring case) or the number shown in parentheses:

               false (0)
                  Fullscreen  layout  is  not used initially, but may be later
                  via menu-selection or control sequence.

               true (1)
                  Fullscreen layout is used initially,  but  may  be  disabled
                  later via menu-selection or control sequence.

               always (2)
                  Fullscreen  layout is used initially, and cannot be disabled
                  later via menu-selection or control sequence.

               never (3)
                  Fullscreen layout is not used, and cannot be  enabled  later
                  via menu-selection or control sequence.

               The default is "false".

       hold (class Hold)
               If true, xterm will not immediately destroy its window when the
               shell command completes.  It will wait until you use the window
               manager  to  destroy/kill  the  window,  or if you use the menu
               entries that send a signal, e.g., HUP or KILL.  You may  scroll
               back,  select text, etc., to perform most graphical operations.
               Resizing the  display  will  lose  data,  however,  since  this
               involves interaction with the shell which is no longer running.

       hpFunctionKeys (class HpFunctionKeys)
               Specifies whether or not HP Function Key escape codes should be
               generated  for  function  keys  instead  of   standard   escape
               sequences.

               See also the keyboardType resource.

       iconGeometry (class IconGeometry)
               Specifies  the  preferred  size and position of the application
               when iconified.  It is not necessarily  obeyed  by  all  window
               managers.

       iconHint (class IconHint)
               Specifies  a  icon  which  will  be added to the window manager
               hints.  xterm provides no default value.

               Set this resource to "none" to omit the  hint  entirely,  using
               whatever the window manager may decide.

               If the iconHint resource is given (or is set via the -n option)
               xterm searches for a pixmap file with that name, in the current
               directory  as  well  as in /usr/share/pixmaps.  if the resource
               does not specify an absolute pathname.   In  each  case,  xterm
               adds  "_48x48" and/or ".xpm" to the filename after trying with-
               out those suffixes.  If it is able to load the file, xterm sets
               the largest of the pixmaps as a default.  That is, "mini.xterm"
               is the same as "mini.xterm_48x48".

               If no explicit iconHint resource is given (or if  none  of  the
               compiled-in  names  matches), xterm uses "mini.xterm" (which is
               always compiled-in).

               The iconHint resource has no effect on "desktop" files, includ-
               ing  "panel" and "menu".  Those are typically set via a ".desk-
               top" file; xterm provides samples for itself  (and  the  uxterm
               script).   The  more capable desktop systems allow changing the
               icon on a per-user basis.

       iconName (class IconName)
               Specifies a label for xterm when iconified.  xterm provides  no
               default  value; some window managers may assume the application
               name, e.g., "xterm".

               Setting the iconName resource sets the icon label unless  over-
               ridden  by  zIconBeep or the control sequences which change the
               window and icon labels.

       keyboardType (class KeyboardType)
               Enables one (or none) of the various  keyboard-type  resources:
               hpFunctionKeys, scoFunctionKeys, sunFunctionKeys, tcapFunction-
               Keys and sunKeyboard.  The resource's value should  be  one  of
               the   corresponding  strings  "hp",  "sco",  "sun",  "tcap"  or
               "vt220".  The individual resources are provided for legacy sup-
               port; this resource is simpler to use.

               The   default  is  "unknown",  i.e.,  none  of  the  associated
               resources are set via this resource.

       maxBufSize (class MaxBufSize)
               Specify the maximum size of the input buffer.  The  default  is
               "32768".   You cannot set this to a value less than the minBuf-
               Size resource.  It will be increased as  needed  to  make  that
               value evenly divide this one.

               On  some  systems  you  may want to increase one or both of the
               maxBufSize and minBufSize resource  values  to  achieve  better
               performance  if  the  operating  system  prefers  larger buffer
               sizes.

       maximized (class Maximized)
               Specifies whether or not xterm should ask the window manager to
               maximize its layout on startup.  The default is "false".

       messages (class Messages)
               Specifies  whether write access to the terminal is allowed ini-
               tially.  See mesg(1).  The default is "true".

       menuLocale (class MenuLocale)
               Specify the locale used  for  character-set  computations  when
               "4096".  You cannot set this to a value less than 64.

       omitTranslation (class OmitTranslation)
               Selectively omit one or more parts of xterm's default  transla-
               tions at startup.  The resource value is a comma-separated list
               of keywords, which may be abbreviated:  "fullscreen",  "scroll-
               lock",  "shift-fonts"  or "wheel-mouse".  Xterm also recognizes
               "default", but omitting that will  make  the  program  unusable
               unless  you  provide a similar definition in your resource set-
               tings.

       ptyHandshake (class PtyHandshake)
               If "true", xterm will perform handshaking during initialization
               to  ensure  that the parent and child processes update the utmp
               and stty state.

               See also  waitForMap  which  waits  for  the  pseudo-terminal's
               notion  of  the  screen  size, and ptySttySize which resets the
               screen size after other terminal  initialization  is  complete.
               The default is "true".

       ptyInitialErase (class PtyInitialErase)
               If  "true",  xterm  will use the pseudo-terminal's sense of the
               stty erase value.  If "false", xterm will set  the  stty  erase
               value  to match its own configuration, using the kb string from
               the termcap entry as a  reference,  if  available.   In  either
               case, the result is applied to the TERMCAP variable which xterm
               sets.

               See also the ttyModes resource, which  may  modify  this.   The
               default is "false".

       ptySttySize (class PtySttySize)
               If "true", xterm will reset the screen size after terminal ini-
               tialization is complete.  This is needed for some systems whose
               pseudo-terminals  cannot  propagate  terminal  characteristics.
               Where it is not needed, it can interfere with other methods for
               setting the intial screen size, e.g., via window manager inter-
               action.

               See also waitForMap which waits for a handshake-message  giving
               the  pseudo-terminal's  notion of the screen size.  The default
               is "false" on Linux and OS X systems, "true" otherwise.

       sameName (class SameName)
               If the value of this resource is "true", xterm  does  not  send
               title and icon name change requests when the request would have
               no effect: the name is not changed.  This has the advantage  of
               preventing  flicker  and the disadvantage of requiring an extra
               round trip to the server to find out the  previous  value.   In
               practice  this  should  never  be  a  problem.   The default is
               "true".

       scaleHeight (class ScaleHeight)

       scoFunctionKeys (class ScoFunctionKeys)
               Specifies  whether  or not SCO Function Key escape codes should
               be generated for  function  keys  instead  of  standard  escape
               sequences.

               See also the keyboardType resource.

       sessionMgt (class SessionMgt)
               If  the value of this resource is "true", xterm sets up session
               manager callbacks for XtNdieCallback and XtNsaveCallback.   The
               default is "true".

       sunFunctionKeys (class SunFunctionKeys)
               Specifies  whether  or not Sun Function Key escape codes should
               be generated for  function  keys  instead  of  standard  escape
               sequences.

               See also the keyboardType resource.

       sunKeyboard (class SunKeyboard)
               Specifies  whether  or  not  Sun/PC  keyboard  layout should be
               assumed rather than DEC VT220.  This causes the keypad  "+'  to
               be mapped to ",'.  and CTRL F1-F12 to F11-F20, depending on the
               setting of the ctrlFKeys resource.  so  xterm  emulates  a  DEC
               VT220  more  accurately.   Otherwise (the default, with sunKey-
               board set to "false"), xterm uses  PC-style  bindings  for  the
               function keys and keypad.

               PC-style  bindings use the Shift, Alt, Control and Meta keys as
               modifiers for function-keys and keypad (see the document  Xterm
               Control  Sequences  for  details).   The  PC-style bindings are
               analogous to PCTerm, but not the same  thing.   Normally  these
               bindings  do  not  conflict  with  the  use  of the Meta key as
               described for the eightBitInput resource.   If  they  do,  note
               that the PC-style bindings are evaluated first.

               See also the keyboardType resource.

       tcapFunctionKeys (class TcapFunctionKeys)
               Specifies  whether  or  not function key escape codes read from
               the termcap/terminfo entry should  be  generated  for  function
               keys  instead  of  standard  escape  sequences.  The default is
               "false", i.e., this feature is disabled.

               See also the keyboardType resource.

       termName (class TermName)
               Specifies the terminal type name to be set in the TERM environ-
               ment variable.

       title (class Title)
               Specifies  a string that may be used by the window manager when
               displaying this application.
               Use ^- to denote undef.  Use \034 to represent ^\, since a lit-
               eral backslash in an X resource escapes the next character.

               This is very useful for overriding the  default  terminal  set-
               tings  without  having  to  do  an  stty every time an xterm is
               started.  Note, however, that the stty program on a given  host
               may use different keywords; xterm's table is built-in.

               If  the  ttyModes  resource  specifies  a value for erase, that
               overrides the ptyInitialErase  resource  setting,  i.e.,  xterm
               initializes the terminal to match that value.

       useInsertMode (class UseInsertMode)
               Force  use  of insert mode by adding appropriate entries to the
               TERMCAP environment variable.  This is  useful  if  the  system
               termcap is broken.  The default is "false".

       utmpDisplayId (class UtmpDisplayId)
               Specifies whether or not xterm should try to record the display
               identifier (display number and screen number) as  well  as  the
               hostname in the system utmp log file.  The default is "true".

       utmpInhibit (class UtmpInhibit)
               Specifies  whether or not xterm should try to record the user's
               terminal in the system utmp log file.  If true, xterm will  not
               try.  The default is "false".

       waitForMap (class WaitForMap)
               Specifies whether or not xterm should wait for the initial win-
               dow map before starting the subprocess.  This is  part  of  the
               ptyHandshake  logic.   When  xterm  is directed to wait in this
               fashion, it passes the terminal size from the  display  end  of
               the  pseudo-terminal  to  the  terminal  I/O  connection, e.g.,
               according to the window manager.  Otherwise, it uses  the  size
               as  given in resource values or command-line option -geom.  The
               default is "false".

       zIconBeep (class ZIconBeep)
               Same as -ziconbeep command line argument.  If the value of this
               resource  is  non-zero, xterms that produce output while iconi-
               fied will cause an XBell sound at the  given  volume  and  have
               "*** "  prepended  to  their icon titles.  Most window managers
               will detect this change immediately, showing you  which  window
               has  the  output.   (A  similar feature was in x10 xterm.)  The
               default is "false".

       zIconTitleFormat (class ZIconTitleFormat)
               Allow customization of the string used in  the  zIconBeep  fea-
               ture.  The default value is "*** %s".

               If  the  resource value contains a "%s", then xterm inserts the
               icon title at that point rather than prepending the  string  to
               the icon title.  (Only the first "%s" is used).

               Specifies  whether  or  not  active icon windows are to be used
               when the xterm window is iconified, if this feature is compiled
               into  xterm.   The active icon is a miniature representation of
               the content of the  window  and  will  update  as  the  content
               changes.   Not all window managers necessarily support applica-
               tion icon windows.  Some window  managers  will  allow  you  to
               enter  keystrokes  into the active icon window.  The default is
               "default".

               Xterm accepts either a keyword (ignoring case)  or  the  number
               shown in parentheses:

               false (0)
                      No active icon is shown.

               true (1)
                      The  active  icon  is  shown.  If you are using twm, use
                      this setting to enable active-icons.

               default (2)
                      xterm checks at startup, and shows an active  icon  only
                      for  window managers which it can identify and which are
                      known to support the feature.  These are fvwm (full sup-
                      port),  and window maker (limited).  A few other windows
                      managers (such as twm and ctwm)  support  active  icons,
                      but  do  not support the extensions which allow xterm to
                      identify the window manager.

       allowBoldFonts (class AllowBoldFonts)
               When set to "false", xterm will not use bold fonts.  This over-
               rides  both  the  alwaysBoldMode  and  the  boldMode resources.
               alwaysBoldMode (class AlwaysBoldMode)

       allowC1Printable (class AllowC1Printable)
               If true, overrides the mapping of C1 controls  (codes  128-159)
               to  make  them be treated as if they were printable characters.
               Although this corresponds to no particular standard, some users
               insist it is a VT100.  The default is "false".

       allowColorOps (class AllowColorOps)
               Specifies  whether control sequences that set/query the dynamic
               colors should be allowed.  ANSI colors are unaffected  by  this
               resource setting.  The default is "true".

       allowFontOps (class AllowFontOps)
               Specifies  whether  control  sequences  that set/query the font
               should be allowed.  The default is "false".

       allowPasteControls (class AllowPasteControls)
            If true, allow control characters  such  as  BEL  and  CAN  to  be
            pasted.   Formatting characters (tab, newline) are always allowed.
            Other C0 control characters are suppressed unless this resource is
            enabled.   The exact set of control characters (C0 and C1) depends
            upon whether UTF-8 encoding is used, as well as the  allowC1Print-
               the current viewport is scrolled past  the  limit  set  by  the
               saveLines resource, then Scroll Lock has no further effect.

               The  reason for setting the default to "false" is to avoid user
               surprise.  This key is generally unused in keyboard  configura-
               tions,  and has not acquired a standard meaning even when it is
               used in that manner.  Consequently, users have assigned it  for
               ad hoc purposes.

       allowSendEvents (class AllowSendEvents)
               Specifies  whether or not synthetic key and button events (gen-
               erated using the X protocol SendEvent request) should be inter-
               preted  or  discarded.  The default is "false" meaning they are
               discarded.  Note that allowing such events would create a  very
               large  security  hole,  therefore enabling this resource force-
               fully disables  the  allowXXXOps  resources.   The  default  is
               "false".

       allowTcapOps (class AllowTcapOps)
               Specifies  whether  control sequences that query the terminal's
               notion of its function-key  strings,  as  termcap  or  terminfo
               capabilities should be allowed.  The default is "true".

               A  few programs, e.g., vim, use this feature to get an accurate
               description of the terminal's capabilities, independent of  the
               termcap/terminfo setting:

               o   xterm can tell the querying program how many colors it sup-
                   ports.  This is a constant, depending on  how  it  is  com-
                   piled,  typically  16.   It  does  not  change if you alter
                   resource settings, e.g., the boldColors resource.

               o   xterm can tell the querying program what strings  are  sent
                   by  modified (shift-, control-, alt-) function- and keypad-
                   keys.  Reporting control- and alt-modifiers  is  a  feature
                   that relies on the ncurses extended naming.

       allowTitleOps (class AllowTitleOps)
               Specifies  whether  control  sequences  that  modify the window
               title or icon name should be allowed.  The default is "true".

       allowWindowOps (class AllowWindowOps)
               Specifies whether extended window control sequences (as used in
               dtterm)  should  be  allowed.   These  include  several control
               sequences which manipulate the window size or position, as well
               as  reporting these values and the title or icon name.  Each of
               these can be abused in a script; curiously enough most terminal
               emulators  that  implement  these restrict only a small part of
               the repertoire.  For fine-tuning, see disallowedWindowOps.  The
               default is "false".

       altIsNotMeta (class AltIsNotMeta)
               If  "true", treat the Alt-key as if it were the Meta-key.  Your
               keyboard may happen to be configured so they are the same.  But
                   preceded by ESC.  This applies as well to function key con-
                   trol  sequences, unless xterm sees that Alt is used in your
                   key translations.

               o   If "false", Alt characters input from the keyboard cause  a
                   shift  to 8-bit characters (just like metaSendsEscape).  By
                   combining the Alt- and Meta-modifiers, you can create  cor-
                   responding combinations of ESC-prefix and 8-bit characters.

               The  default is "False".  Xterm provides a menu option for tog-
               gling this resource.

       alternateScroll (class ScrollCond)
               If "true", the scroll-back and scroll-forw  actions  send  cur-
               sor-up  and  -down  keys when xterm is displaying the alternate
               screen.  The default is "false".

               The alternateScroll state can  also  be  set  using  a  control
               sequence.

       alwaysBoldMode (class AlwaysBoldMode)
               Specifies  whether  xterm  should  check if the normal and bold
               fonts are distinct before deciding whether to use  overstriking
               to  simulate  bold fonts.  If this resource is true, xterm does
               not make the check for distinct fonts when deciding how to han-
               dle the boldMode resource.  The default is "false".

               boldMode   alwaysBoldMode   Comparison   Action
               ----------------------------------------------------
               false      false            ignored      use font
               false      true             ignored      use font

               This resource is used only for bitmap fonts:

               o   When  using  bitmap  fonts,  it  is  possible that the font
                   server will approximate the bold font by rescaling it  from
                   a  different  font  size than expected.  The alwaysBoldMode
                   resource allows the user to override the  (sometimes  poor)
                   resulting  bold  font  with overstriking (which is at least
                   consistent).

               o   The problem does not  occur  with  TrueType  fonts  (though
                   there  can  be  other  unnecessary issues such as different
                   coverage of the normal and bold fonts).

               As an alternative, setting the allowBoldFonts resource to false
               overrides both the alwaysBoldMode and the boldMode resources.

       alwaysHighlight (class AlwaysHighlight)
               Specifies  whether  or  not xterm should always display a high-
               lighted text cursor.  By default (if this resource is false), a

       answerbackString (class AnswerbackString)
               Specifies  the  string  that  xterm sends in response to an ENQ
               (control/E) character from the host.  The default  is  a  blank
               string,  i.e., "".  A hardware VT100 implements this feature as
               a setup option.

       appcursorDefault (class AppcursorDefault)
               If "true", the cursor keys are initially in  application  mode.
               This  is the same as the VT102 private DECCKM mode, The default
               is "false".

       appkeypadDefault (class AppkeypadDefault)
               If "true", the keypad keys are initially in  application  mode.
               The default is "false".

       assumeAllChars (class AssumeAllChars)
               If "true", this enables a special case in bitmap fonts to allow
               the font server to choose how to display missing  glyphs.   The
               default is "false".

       autoWrap (class AutoWrap)
               Specifies  whether  or  not  auto-wraparound should be enabled.
               This is the same as the VT102 DECAWM.  The default is "true".

       awaitInput (class AwaitInput)
               Specifies whether or not the xterm uses a 50 millisecond  time-
               out  to  await  input (i.e., to support the Xaw3d arrow scroll-
               bar).  The default is "false".

       backarrowKey (class BackarrowKey)
               Specifies whether the backarrow key transmits a  backspace  (8)
               or delete (127) character.  This corresponds to the DECBKM con-
               trol  sequence.   A  "true"  value  specifies  backspace.   The
               default  is  "True".   Pressing  the  control  key toggles this
               behavior.

       background (class Background)
               Specifies the color to use for the background  of  the  window.
               The default is "XtDefaultBackground".

       bellIsUrgent (class BellIsUrgent)
               Specifies  whether  to set the Urgency hint for the window man-
               ager when making a bell sound.  The default is "false".

       bellOnReset (class BellOnReset)
               Specifies whether to sound a bell when doing a hard reset.  The
               default is "true".

       bellSuppressTime (class BellSuppressTime)
               Number  of  milliseconds  after  a  bell command is sent during
               which additional bells will be suppressed.  Default is 200.  If
               set  non-zero,  additional  bells will also be suppressed until
               the server reports that processing of the first bell  has  been
               This font must be the same height and width as the normal font,
               otherwise it is ignored.  If only one of  the  normal  or  bold
               fonts  is specified, it will be used as the normal font and the
               bold font will be produced by overstriking this font.

               See  also  the  discussion  of  boldMode   and   alwaysBoldMode
               resources.

       boldMode (class BoldMode)
               This  specifies  whether  or  not  text with the bold attribute
               should be overstruck to simulate bold  fonts  if  the  resolved
               bold  font is the same as the normal font.  It may be desirable
               to disable bold fonts when color is being  used  for  the  bold
               attribute.

               Note that xterm has one bold font which you may set explicitly.
               Xterm attempts to derive a bold font for the other font  selec-
               tions (font1 through font6).  If it cannot find a bold font, it
               will use the normal font.  In each case (whether  the  explicit
               resource or the derived font), if the normal and bold fonts are
               distinct, this resource has no effect.  The default is "true".

               See the alwaysBoldMode resource which can modify  the  behavior
               of this resource.

               Although  xterm  attempts  to derive a bold font for other font
               selections, the font server may not  cooperate.   Since  X11R6,
               bitmap  fonts have been scaled.  The font server claims to pro-
               vide the bold font that xterm requests, but the result  is  not
               always  readable.   XFree86  introduced  a feature which can be
               used to suppress the scaling.  In the X server's  configuration
               file (e.g., "/etc/X11/XFree86"), you can add ":unscaled" to the
               end of the directory specification for the "misc" fonts,  which
               comprise  the  fixed-pitch  fonts  that are used by xterm.  For
               example

                   FontPath                 "/usr/lib/X11/fonts/misc/"

               would become

                   FontPath                 "/usr/lib/X11/fonts/misc/:unscaled"

               Depending on your configuration, the font server may  have  its
               own  configuration  file.  The same ":unscaled" can be added to
               its configuration file at the end of the  directory  specifica-
               tion for "misc".

               The  bitmap  scaling feature is also used by xterm to implement
               VT102 double-width and double-height characters.

       brokenLinuxOSC (class BrokenLinuxOSC)
               If true, xterm applies a workaround to ignore malformed control
               sequences  that a Linux script might send.  Compare the palette
               control sequences documented  in  console_codes  with  ECMA-48.
               application  control string without completing it.  Set this to
               "true" if xterm appears to freeze when connecting.  The default
               is "false".

               Xterm's  state  parser  recognizes  several  types  of  control
               strings which can contain text, e.g.,

               APC (Application Program Command),
               DCS (Device Control String),
               OSC (Operating System Command),
               PM (Privacy Message), and
               SOS (Start of String),

               Each should end with a string-terminator (a  special  character
               which  cannot appear in these strings).  Ordinary control char-
               acters found within the string are not ignored; they  are  pro-
               cessed without interfering with the process of accumulating the
               control string's content.  Xterm recognizes these  controls  in
               all  modes,  although  some  of the functions may be suppressed
               after parsing the control.

               When enabled, this feature allows the  user  to  exit  from  an
               unterminated  control string when any of these ordinary control
               characters are found:

               control/D (used as an end of file in many shells),
               control/H (backspace),
               control/I (tab-feed),
               control/J (line feed aka newline),
               control/K (vertical tab),
               control/L (form feed),
               control/M (carriage return),
               control/N (shift-out),
               control/O (shift-in),
               control/Q (XOFF),
               control/X (cancel)

       c132 (class C132)
               Specifies whether or not the  VT102  DECCOLM  escape  sequence,
               used  to  switch between 80 and 132 columns, should be honored.
               The default is "false".

       cacheDoublesize (class CacheDoublesize)
               Tells whether to cache double-sized fonts by xterm.   Set  this
               to zero to disable double-sized fonts altogether.

       cdXtraScroll (class CdXtraScroll)
               Specifies whether xterm should scroll to a new page when clear-
               ing the whole screen.  Like tiXtraScroll, the  intent  of  this
               option is to provide a picture of the full-screen application's
               display on the scrollback before  wiping  out  the  text.   The
               default for this resource is "false".

       charClass (class CharClass)
               is false, the mkWidth resource controls the choice between  the
               system's  wcwidth  and xterm's built-in tables.  The default is
               "false".

       color0 (class Color0)

       color1 (class Color1)

       color2 (class Color2)

       color3 (class Color3)

       color4 (class Color4)

       color5 (class Color5)

       color6 (class Color6)

       color7 (class Color7)
               These specify the  colors  for  the  ISO-6429  extension.   The
               defaults  are,  respectively,  black,  red3, green3, yellow3, a
               customizable dark  blue,  magenta3,  cyan3,  and  gray90.   The
               default  shades of color are chosen to allow the colors 8-15 to
               be used as brighter versions.

       color8 (class Color8)

       color9 (class Color9)

       color10 (class Color10)

       color11 (class Color11)

       color12 (class Color12)

       color13 (class Color13)

       color14 (class Color14)

       color15 (class Color15)
               These specify the colors for the ISO-6429 extension if the bold
               attribute  is  also  enabled.   The default resource values are
               respectively, gray30, red, green, yellow, a customizable  light
               blue, magenta, cyan, and white.

       color16 (class Color16)

       through

       color255 (class Color255)
               These  specify  the  colors  for  the 256-color extension.  The
               default resource values are for colors 16 through 231 to make a
               6x6x6  color  cube,  and  colors  232  through  255  to  make a
               grayscale ramp.
               entire range for 88-colors.

       colorAttrMode (class ColorAttrMode)
               Specifies whether colorBD, colorBL, colorRV, and colorUL should
               override ANSI colors.  If not, these are displayed only when no
               ANSI  colors have been set for the corresponding position.  The
               default is "false".

       colorBD (class ColorBD)
               This specifies the color to use to display bold  characters  if
               the  "colorBDMode"  resource is enabled.  The default is "XtDe-
               faultForeground".

               See also the veryBoldColors  resource  which  allows  combining
               bold and color.

       colorBDMode (class ColorAttrMode)
               Specifies  whether characters with the bold attribute should be
               displayed in color or as bold characters.   Note  that  setting
               colorMode off disables all colors, including bold.  The default
               is "false".

       colorBL (class ColorBL)
               This specifies the color to use to display blink characters  if
               the  "colorBLMode"  resource is enabled.  The default is "XtDe-
               faultForeground".

               See also the veryBoldColors  resource  which  allows  combining
               underline and color.

       colorBLMode (class ColorAttrMode)
               Specifies whether characters with the blink attribute should be
               displayed in color.  Note that setting colorMode  off  disables
               all colors, including this.  The default is "false".

       colorMode (class ColorMode)
               Specifies  whether  or not recognition of ANSI (ISO-6429) color
               change escape sequences should  be  enabled.   The  default  is
               "true".

       colorRV (class ColorRV)
               This  specifies  the color to use to display reverse characters
               if the "colorRVMode"  resource  is  enabled.   The  default  is
               "XtDefaultForeground".

               See  also  the  veryBoldColors  resource which allows combining
               reverse and color.

       colorRVMode (class ColorAttrMode)
               Specifies whether characters with the reverse attribute  should
               be  displayed  in  color.  Note that setting colorMode off dis-
               ables all colors, including this.  The default is "false".

       colorUL (class ColorUL)

       combiningChars (class CombiningChars)
               Specifies the number of wide-characters which can be stored  in
               a  cell  to overstrike (combine) with the base character of the
               cell.  This can be set to values in the  range  0  to  4.   The
               default is "2".

       ctrlFKeys (class CtrlFKeys)
               In  VT220  keyboard  mode (see sunKeyboard resource), specifies
               the amount by which to shift F1-F12 given  a  control  modifier
               (CTRL).  This allows you to generate key symbols for F10-F20 on
               a Sun/PC keyboard.  The default is "10", which means that  CTRL
               F1 generates the key symbol for F11.

       curses (class Curses)
               Specifies  whether or not the last column bug in more(1) should
               be worked around.  See the -cu option for details.  The default
               is "false".

       cursorBlink (class CursorBlink)
               Specifies  whether  to  make  the cursor blink.  The default is
               "false".

               Xterm uses  two  variables  to  determine  whether  the  cursor
               blinks.  One is set by this resource.  The other is set by con-
               trol sequences (private mode 12 and DECSCUSR).  Xterm tests the
               XOR of the two variables.

       cursorColor (class CursorColor)
               Specifies the color to use for the text cursor.  The default is
               "XtDefaultForeground".  By default, xterm attempts to keep this
               color  from  being  the  same as the background color, since it
               draws the cursor by filling the background of a text cell.  The
               same  restriction applies to control sequences which may change
               this color.

               Setting this resource overrides most of xterm's adjustments  to
               cursor color.  It will still use reverse-video to disallow some
               cases, such as a black cursor on a black background.

       cursorOffTime (class CursorOffTime)
               Specifies the duration of the "off" part of  the  cursor  blink
               cycle-time  in  milliseconds.   The same timer is used for text
               blinking.  The default is "300".

       cursorOnTime (class CursorOnTime)
               Specifies the duration of the "on" part  of  the  cursor  blink
               cycle-time,  in  milliseconds.  The same timer is used for text
               blinking.  The default is "600".

       cutNewline (class CutNewline)
               If "false", triple clicking to select a line does  not  include
               the  Newline at the end of the line.  If "true", the Newline is
               selected.  The default is "true".
               used to  determine  the  type  of  response  to  a  DA  control
               sequence.   Leading  non-digit  characters  are  ignored, e.g.,
               "vt100" and "100" are the same.  The default is "420".

       defaultString (class DefaultString)
               Specify the character (or string) which xterm  will  substitute
               when  pasted  text  includes a character which cannot be repre-
               sented in the current encoding.  For  instance,  pasting  UTF-8
               text  into a display of ISO-8859-1 characters will only be able
               to display codes 0-255, while UTF-8 text  can  include  Unicode
               values above 255.  The default is "#" (a single pound sign).

               If the undisplayable text would be double-width, xterm will add
               a space after the "#" character, to give roughly the same  lay-
               out on the screen as the original text.

       deleteIsDEL (class DeleteIsDEL)
               Specifies  whether  the Delete key on the editing keypad should
               send DEL (127) or the VT220-style Remove  escape  sequence.   A
               "false" value enables the latter.  The default is "Maybe".

       disallowedColorOps (class DisallowedColorOps)
               Specify  which  features  will  be disabled if allowColorOps is
               false.  This is a comma-separated list of names.   The  default
               value is
               SetColor,GetColor,GetAnsiColor

               The  names are listed below.  xterm ignores capitalization, but
               they are shown in mixed-case for clarity.

               SetColor
                    Set a specific dynamic color.

               GetColor
                    Report the current setting of a given dynamic color.

               GetAnsiColor
                    Report the current setting of a given ANSI color (actually
                    any of the colors set via ANSI-style controls).

       disallowedFontOps (class DisallowedFontOps)
               Specify  which  features  will  be  disabled if allowFontOps is
               false.  This is a comma-separated list of names.   The  default
               value is
               SetFont,GetFont

               The  names are listed below.  xterm ignores capitalization, but
               they are shown in mixed-case for clarity.

               SetFont
                    Set the specified font.

               GetFont
                    Report the specified font.

               GetTcap
                    Report specified function- and other special keys.

       disallowedWindowOps (class DisallowedWindowOps)
               Specify  which  features  will be disabled if allowWindowOps is
               false.  This is a comma-separated list of names,  or  (for  the
               controls  adapted  from  dtterm  the  operation  number).   The
               default value is
               1,2,3,4,5,6,7,8,9,11,13,14,18,19,20,21,GetSelection,SetSelec-
               tion,SetWinLines,SetXprop
       (i.e. no operations are allowed).

               The  names are listed below.  xterm ignores capitalization, but
               they are shown in mixed-case for clarity.  Where a  number  can
               be used as an alternative, it is given in parentheses after the
               name.

               GetIconTitle (20)
                    Report xterm window's icon label as a string.

               GetWinSizeChars (18)
                    Report the size of the text area in characters as numbers.

               GetWinSizePixels (14)
                    Report xterm window in pixels as numbers.

               GetWinState (11)
                    Report xterm window state as a number.

               GetWinTitle (21)
                    Report xterm window's title as a string.

               LowerWin (6)
                    Lower the xterm window  to  the  bottom  of  the  stacking
                    order.

               MaximizeWin (9)
                    Maximize window (i.e., resize to screen size).

               FullscreenWin (10)
                    Use full screen (i.e., resize to screen size, without win-
                    dow decorations).

               MinimizeWin (2)
                    Refresh the xterm window.

               RestoreWin (1)

               SetXprop
                    Set X property on top-level window.

       dynamicColors (class DynamicColors)
               Specifies whether or not  escape  sequences  to  change  colors
               assigned to different attributes are recognized.

       eightBitControl (class EightBitControl)
               Specifies whether or not control sequences sent by the terminal
               should  be  eight-bit  characters  or  escape  sequences.   The
               default is "false".

       eightBitInput (class EightBitInput)
               If  "true",  Meta  characters (a single-byte character combined
               with the Meta modifier key) input from the  keyboard  are  pre-
               sented  as a single character, modified according to the eight-
               BitMeta resource.  If "false", Meta  characters  are  converted
               into  a  two-character  sequence with the character itself pre-
               ceded by ESC.  The default is "true".

               The metaSendsEscape and altSendsEscape resources  may  override
               this  feature.   Generally  keyboards do not have a key labeled
               "Meta", but "Alt" keys are common, and they are  conventionally
               used  for  "Meta".  If they were synonymous, it would have been
               reasonable to name this  resource  "altSendsEscape",  reversing
               its  sense.  For more background on this, see the meta function
               in curses.

               Note that the Alt key is not necessarily the same as  the  Meta
               modifier.   xmodmap  lists your key modifiers.  X defines modi-
               fiers for shift, (caps) lock and control, as well  as  5  addi-
               tional modifiers which are generally used to configure key mod-
               ifiers.  xterm inspects the same information to find the  modi-
               fier  associated with either Meta key (left or right), and uses
               7-bit mode.  For  some  configurations  this  is  unsuccessful;
               failure  is  ignored.  After startup, xterm does not change the
               terminal between 8-bit and 7-bit mode.

               As originally implemented in X11, the resource  value  did  not
               change after startup.  However (since patch #216 in 2006) xterm
               can modify eightBitInput after startup via a control  sequence.
               The corresponding terminfo capabilities smm (set meta mode) and
               rmm (reset meta mode) have been recognized  by  bash  for  some
               time.   Interestingly enough, bash's notion of "meta mode" dif-
               fers from the standard definition  (in  the  terminfo  manual),
               which  describes  the  change to the eighth bit of a character.
               It happens that bash views "meta mode"  as  the  ESC  character
               that  xterm  puts before a character when a special meta key is
               pressed.  bash's early documentation talks about the ESC  char-
               acter and ignores the eighth bit.

       eightBitMeta (class EightBitMeta)
               This  controls  the way xterm modifies the eighth bit of a sin-
               gle-byte key when  the  eightBitInput  resource  is  set.   The
               default is "locale".

               The  resource  value  is a string, evaluated as a boolean after
               startup.

               false
                    The key is sent unmodified.

               locale
                    The key is modified only  if  the  locale  uses  eight-bit
                    encoding.

               true The key is sent modified.

               never
                    The key is always sent unmodified.

               Except for the never choice, xterm honors the terminfo capabil-
               ities smm (set meta mode) and rmm (reset meta  mode),  allowing
               the feature to be turned on or off dynamically.

               If  eightBitMeta  is  enabled when the locale uses UTF-8, xterm
               encodes the value as UTF-8 (since patch #183 in 2003).

       eightBitOutput (class EightBitOutput)
               Specifies whether or not eight-bit  characters  sent  from  the
               host  should  be  accepted as is or stripped when printed.  The
               default is "true", which means that they are accepted as is.

       eightBitSelectTypes (class EightBitSelectTypes)
               Override   xterm's   default   selection   target   list   (see
               SELECT/PASTE)  for selections in normal (ISO-8859-1) mode.  The
               default is an empty string, i.e., "", which does  not  override
               anything.
                   #!/bin/sh
                   FONT=`xfontsel -print`
                   test -n "$FONT" && xfd -fn "$FONT"

               However  (even  though  xfd  accepts  a  "-fa" option to denote
               FreeType fonts), xfontsel has not been similarly extended.   As
               a workaround, you may try

                   fc-list :scalable=true:spacing=mono: family

               to  find a list of scalable fixed-pitch fonts which may be used
               for the faceName resource value.

       faceNameDoublesize (class FaceNameDoublesize)
               Specify a double-width scalable font for cases where an  appli-
               cation  requires  this, e.g., in CJK applications.  There is no
               default value.

               If  the  application  uses  double-wide  characters  and   this
               resource  is  not given, xterm will use a scaled version of the
               font given by faceName.

       faceSize (class FaceSize)
               Specify the pointsize for  fonts  selected  from  the  FreeType
               library  if  support  for that library was compiled into xterm.
               The default is "14.0" On the VT Fonts menu, this corresponds to
               the Default entry.

               Although the default is "14.0", this may not be the same as the
               pointsize for the default bitmap font, i.e., that assigned with
               the -fn option, or the font resource.  For example, the "fixed"
               font usually has a pointsize of "8.0".  If you set faceSize  to
               match  the size of the bitmap font, then switching between bit-
               map and TrueType fonts via the font menu will  give  comparable
               sizes for the window.

               You  can specify the pointsize for TrueType fonts selected with
               the other size-related menu entries such as Medium, Huge, etc.,
               by  using  one of the following resource values.  If you do not
               specify a value, they default to "0.0", which causes  xterm  to
               use  the ratio of font sizes from the corresponding bitmap font
               resources to obtain a TrueType pointsize.

               If all of the faceSize resources are set, then xterm  will  use
               this  information to determine the next smaller/larger TrueType
               font for the larger-vt-font()  and  smaller-vt-font()  actions.
               If any are not set, xterm will use only the areas of the bitmap
               fonts.

       faceSize1 (class FaceSize1)
               Specifies the pointsize of the first alternative font.

       faceSize2 (class FaceSize2)
               Specifies the pointsize of the second alternative font.

       font (class Font)
               Specifies the name of the normal font.  The default is "fixed".

               See the discussion of the locale resource, which describes  how
               this font may be overridden.

               NOTE: some resource files use patterns such as

                   *font: fixed

               which are overly broad, affecting both

                   xterm.vt100.font

               and

                   xterm.vt100.utf8Fonts.font

               which is probably not what you intended.

       fastScroll (class FastScroll)
               Modifies  the effect of jump scroll (jumpScroll) by suppressing
               screen refreshes for the special case when output to the screen
               has  completely shifted the contents off-screen.  For instance,
               cat'ing a large file to the screen does this.

       font1 (class Font1)
               Specifies the name of the first alternative font, corresponding
               to "Unreadable" in the standard menu.

       font2 (class Font2)
               Specifies  the name of the second alternative font, correspond-
               ing to "Tiny" in the standard menu.

       font3 (class Font3)
               Specifies the name of the third alternative font, corresponding
               to "Small" in the standard menu.

       font4 (class Font4)
               Specifies  the name of the fourth alternative font, correspond-
               ing to "Medium" in the standard menu.

       font5 (class Font5)
               Specifies the name of the fifth alternative font, corresponding
               to "Large" in the standard menu.

       font6 (class Font6)
               Specifies the name of the sixth alternative font, corresponding
               to "Huge" in the standard menu.

       fontDoublesize (class FontDoublesize)
               Specifies whether xterm should attempt to use font  scaling  to
               draw  double-sized  characters.  Some older font servers cannot
                    setting.

               2    Always report an error on failure to load a font.

               The default is "1".

       forceBoxChars (class ForceBoxChars)
               Specifies whether xterm should assume the normal and bold fonts
               have VT100 line-drawing characters:

               o   The fixed-pitch ISO-8859-*-encoded fonts used by xterm nor-
                   mally  have  the  VT100  line-drawing glyphs in cells 1-31.
                   Other fixed-pitch fonts may be more  attractive,  but  lack
                   these glyphs.

               o   When  using  an ISO-10646-1 font and the wideChars resource
                   is true, xterm uses the  Unicode  glyphs  which  match  the
                   VT100 line-drawing glyphs.

               If  "false",  xterm  checks  for missing glyphs in the font and
               makes line-drawing characters directly as needed.   If  "true",
               xterm  assumes the font does not contain the line-drawing char-
               acters, and draws them directly.  The default is "false".

       forcePackedFont (class ForcePackedFont)
               Specifies whether xterm should use the maximum or minimum glyph
               width  when  displaying  using  a bitmap font.  Use the maximum
               width to help with proportional fonts.  The default is  "true",
               denoting the minimum width.

       foreground (class Foreground)
               Specifies  the  color to use for displaying text in the window.
               Setting the class name instead of the instance name is an  easy
               way  to  have everything that would normally appear in the text
               color change color.  The default is "XtDefaultForeground".

       formatOtherKeys (class FormatOtherKeys)
               Overrides the format of the escape sequence used to report mod-
               ified keys with the modifyOtherKeys resource.

               0  send   modified  keys  as  parameters  for  function-key  27
                  (default).

               1  send modified keys as parameters for CSI u.

       freeBoldBox (class FreeBoldBox)
               Specifies whether xterm should assume the  bounding  boxes  for
               normal  and  bold fonts are compatible.  If "false", xterm com-
               pares them and will reject choices of bold fonts  that  do  not
               match  the  size  of  the normal font.  The default is "false",
               which means that the comparison is performed.

       geometry (class Geometry)
               Specifies the preferred size and position of the VT102  window.
               xterm checks if those resources are set to something other than
               the default foreground and  background  colors.   Setting  this
               resource disables the check.

               The  following  table shows the interaction of the highlighting
               resources, abbreviated as shown to fit in this page:

               ------------------------------------------------------

       highlightReverse (class HighlightReverse)
               Specifies whether xterm should reverse the selection foreground
               and  background  colors  when selecting text with reverse-video
               Depending  on  the  way  your applications write to the screen,
               there may be trailing blanks on a line.  Xterm stores  data  as
               it  is  shown  on  the screen.  Erasing the display changes the
               internal state of each cell so it is not considered a blank for
               the  purpose of selection.  Blanks written since the last erase
               are selectable.  If you do not wish to have trailing blanks  in
               a selection, use the trimSelection resource.

       highlightTextColor (class HighlightTextColor)
               Specifies  the  color  to  use  for  the foreground of selected
               (highlighted) text.   If  not  specified  (i.e.,  matching  the
               default  background),  reverse  video  is used.  The default is
               "XtDefaultBackground".

       hpLowerleftBugCompat (class HpLowerleftBugCompat)
               Specifies whether to work around  a  bug  in  HP's  xdb,  which
               ignores  termcap  and  always  sends ESC F to move to the lower
               left corner.  "true" causes xterm  to  interpret  ESC  F  as  a
               request  to  move  to the lower left corner of the screen.  The
               default is "false".

       i18nSelections (class I18nSelections)
               If false, xterm will not request the targets  COMPOUND_TEXT  or
               TEXT.   The  default is "true". It may be set to false in order
               to work around ICCCM violations by other X clients.

       iconBorderColor (class BorderColor)
               Specifies the border color for the active icon window  if  this
               feature  is  compiled into xterm.  Not all window managers will
               make the icon border visible.

       iconBorderWidth (class BorderWidth)
               Specifies the border width for the active icon window  if  this
               feature  is  compiled into xterm.  The default is "2".  Not all
               window managers will make the border visible.

       iconFont (class IconFont)
               Specifies the font for the miniature  active  icon  window,  if
               this feature is compiled into xterm.  The default is "nil2".

       initialFont (class InitialFont)
               Specifies  which  of  the VT100 fonts to use initially.  Values
               are the same as for the set-vt-font  action.   The  default  is
               "d", i.e., "default".

       inputMethod (class XtCInputMethod)
               Tells  xterm  which  type  of input method to use.  There is no
               default method.

       internalBorder (class BorderWidth)
               Specifies the number of pixels between the characters  and  the
               window border.  The default is "2".

       italicULMode (class ColorAttrMode)
               default is "true".

       keyboardDialect (class KeyboardDialect)
               Specifies  the initial keyboard dialect, as well as the default
               value when the terminal is reset.  The value given is the  same
               as  the  final  character in the control sequences which change
               character sets.  The default is "B", which  corresponds  to  US
               ASCII.

       nameKeymap (class NameKeymap)
               See the discussion of the keymap() action.

       limitResize (class LimitResize)
               Limits  resizing  of the screen via control sequence to a given
               multiple of the display dimensions.  The default is "1".

       locale (class Locale)
               Specifies how to use luit, an encoding converter between  UTF-8
               and  locale  encodings.  The resource value (ignoring case) may
               be:

               true
                   xterm  will  use  the  encoding  specified  by  the  users'
                   LC_CTYPE locale (i.e., LC_ALL, LC_CTYPE, or LANG variables)
                   as far as possible.  This is realized  by  always  enabling
                   UTF-8 mode and invoking luit in non-UTF-8 locales.

               medium
                   xterm  will  follow  users' LC_CTYPE locale only for UTF-8,
                   east Asian, and Thai locales, where the encodings were  not
                   supported  by  conventional  8bit mode with changing fonts.
                   For other locales, xterm will use conventional 8bit mode.

               checkfont
                   If mini-luit is compiled-in, xterm will check if a  Unicode
                   font has been specified.  If so, it checks if the character
                   encoding for  the  current  locale  is  POSIX,  Latin-1  or
                   Latin-9, uses the appropriate mapping to support those with
                   the Unicode font.  For other encodings, xterm assumes  that
                   UTF-8 encoding is required.

               false
                   xterm will use conventional 8bit mode or UTF-8 mode accord-
                   ing to utf8 resource or -u8 option.

               Any other value, e.g., "UTF-8" or "ISO8859-2", is assumed to be
               an encoding name; luit will be invoked to support the encoding.
               The actual list of supported encodings depends  on  luit.   The
               default is "medium".

               Regardless of your locale and encoding, you need an ISO-10646-1
               font to display the result.  Your configuration may not include
               this  font,  or  locale-support by xterm may not be needed.  At
               startup, xterm uses a  mechanism  equivalent  to  the  load-vt-
               locale resource.  The help message shown by "xterm -help" lists
               the default value, which depends on your system configuration.

               If the encoding converter requires command-line parameters, you
               can add those after the command, e.g.,

                   *localeFilter: xterm-filter -p

               Alternatively, you may  put  those  parameter  within  a  shell
               script to execute the converter, and set this resource to point
               to the shell script.

               When using a locale-filter, e.g., with the -e  option,  or  the
               shell,  xterm  first tries passing control via that filter.  If
               it fails, xterm will retry without  the  locale-filter.   Xterm
               warns about the failure before retrying.

       loginShell (class LoginShell)
               Specifies  whether  or  not  the  shell to be run in the window
               should be started as a login shell.  The default is "false".

       marginBell (class MarginBell)
               Specifies whether or not the bell should be rung when the  user
               types near the right margin.  The default is "false".

       metaSendsEscape (class MetaSendsEscape)
               If  "true", Meta characters (a character combined with the Meta
               modifier key) are converted into a two-character sequence  with
               the  character itself preceded by ESC.  This applies as well to
               function key control sequences, unless xterm sees that Meta  is
               used  in  your  key  translations.  If "false", Meta characters
               input from the keyboard are handled according to the  eightBit-
               Input resource.  The default is "False".

       mkSamplePass (class MkSamplePass)
               If  mkSampleSize  is  nonzero,  and  mkWidth (and cjkWidth) are
               false, on startup xterm compares its  built-in  tables  to  the
               system's wide character width data to decide if it will use the
               system's data.  It tests the first mkSampleSize character  val-
               ues,  and  allows up to mkSamplePass mismatches before the test
               fails.  The default (for the allowed number of  mismatches)  is
               256.

       mkSampleSize (class MkSampleSize)
               With  mkSamplePass, this specifies a startup test used for ini-
               tializing wide character width calculations.  The default (num-
               ber of characters to check) is 1024.

       mkWidth (class MkWidth)
               Specifies  whether  xterm  should use a built-in version of the
               wide  character  width  calculation.   See  also  the  cjkWidth
               resource which can override this.  The default is "false".

               Here  is a summary of the resources which control the choice of
               escape sequence returned by a cursor-key.  The default is "2":

               -1   disables the feature.

               0    uses the old/obsolete behavior.

               1    prefixes modified sequences with CSI.

               2    forces the modifier to be the second parameter if it would
                    otherwise be the first.

               3    marks the sequence with a ">" to hint that it is private.

       modifyFunctionKeys (class ModifyFunctionKeys)
               Tells  how  to  handle the special case where Control-, Shift-,
               Alt- or Meta-modifiers are used  to  add  a  parameter  to  the
               escape  sequence  returned  by  a (numbered) function-key.  The
               default is "2".  The resource values are similar to  modifyCur-
               sorKeys:

               -1   permits  the  user  to use shift- and control-modifiers to
                    construct function-key strings using the  normal  encoding
                    scheme.

               0    uses the old/obsolete behavior.

               1    prefixes modified sequences with CSI.

               2    forces the modifier to be the second parameter if it would
                    otherwise be the first.

               3    marks the sequence with a ">" to hint that it is private.

               If modifyFunctionKeys is zero, xterm uses Control-  and  Shift-
               modifiers to allow the user to construct numbered function-keys
               beyond the set provided by the keyboard:

               Control
                    adds the value given by the ctrlFKeys resource.

               Shift
                    adds twice the value given by the ctrlFKeys resource.

               Control/Shift
                    adds  three  times  the  value  given  by  the   ctrlFKeys
                    resource.

       modifyKeyboard (class ModifyKeyboard)
               Normally xterm makes a special case regarding modifiers (shift,
               control, etc.)  to handle special keyboard layouts (legacy  and
               vt220).   This  is done to provide compatible keyboards for DEC
               VT220 and related terminals that  implement  user-defined  keys
               (UDK).

               4    allows  modification  of  function-keys,  overrides use of
                    Shift-modifier for UDK.

               8    allows modification of other special keys

       modifyOtherKeys (class ModifyOtherKeys)
               Like modifyCursorKeys,  tells  xterm  to  construct  an  escape
               sequence  for  other  keys  (such as "2") when modified by Con-
               trol-, Alt- or Meta-modifiers.  This feature does not apply  to
               function  keys and well-defined keys such as ESC or the control
               keys.  The default is "0":

               0    disables this feature.

               1    enables this feature for keys except for those with  well-
                    known behavior, e.g., Tab, Backarrow and some special con-
                    trol character cases, e.g., Control-Space to make a NUL.

               2    enables this feature for  keys  including  the  exceptions
                    listed.

       multiClickTime (class MultiClickTime)
               Specifies  the maximum time in milliseconds between multi-click
               select events.  The default is "250" milliseconds.

       multiScroll (class MultiScroll)
               Specifies  whether  or  not  scrolling  should  be  done  asyn-
               chronously.  The default is "false".

       nMarginBell (class Column)
               Specifies  the  number  of  characters from the right margin at
               which the margin bell should  be  rung,  when  enabled  by  the
               marginBell resource.  The default is "10".

       numLock (class NumLock)
               If  "true",  xterm checks if NumLock is used as a modifier (see
               xmodmap(1)).  If so, this modifier  is  used  to  simplify  the
               logic  when  implementing  special  NumLock for the sunKeyboard
               resource.  Also (when sunKeyboard is false), similar  logic  is
               used  to  find  the modifier associated with the left and right
               Alt keys.  The default is "true".

       oldXtermFKeys (class OldXtermFKeys)
               If "true", xterm will use old-style control sequences for func-
               tion  keys F1 to F4, for compatibility with X Consortium xterm.
               Otherwise, it uses the VT100-style codes for PF1 to  PF4.   The
               default is "false".

       on2Clicks (class On2Clicks)

       on3Clicks (class On3Clicks)

       on4Clicks (class On4Clicks)

               line
                  Select a line (counting wrapping).

               group
                  Select  a  group of adjacent lines (counting wrapping).  The
                  selection stops on a blank line, and does not extend outside
                  the current page.

               page
                  Select all visible lines, i.e., the page.

               all
                  Select all lines, i.e., including the saved lines.

               regex
                  Select  a  "word"  as  determined  by the regular expression
                  which follows in the resource value.

               none
                  No selection action is associated with this resource.  xterm
                  interprets  it as the end of the list.  For example, you may
                  use it to disable triple (and higher)  clicking  by  setting
                  on3Clicks to "none".

               The  default  values for on2Clicks and on3Clicks are "word" and
               "line", respectively.  There is no default value for  on4Clicks
               or  on5Clicks, making those inactive.  On startup, xterm deter-
               mines the maximum number of clicks by  the  onXClicks  resource
               values which are set.

       openIm (class XtCOpenIm)
               Tells  xterm  whether to open the input method at startup.  The
               default is "true".

       pointerColor (class PointerColor)
               Specifies the foreground color of the pointer.  The default  is
               "XtDefaultForeground".

       pointerColorBackground (class PointerColorBackground)
               Specifies  the background color of the pointer.  The default is
               "XtDefaultBackground".

       pointerMode (class PointerMode)
               Specifies when the pointer may be hidden as the user types.  It
               will  be redisplayed if the user moves the mouse, or clicks one
               of its buttons.

               0  never

               1  the application running in xterm  has  not  activated  mouse
                  mode.  This is the default.

               2  always.

       precompose (class XtCPrecompose)
               Tells xterm whether to precompose UTF-8 data into Normalization
               Form C, which combines commonly-used accents onto base  charac-
               ters.   If  it does not do this, accents are left as separatate
               characters.  The default is "true".

       preeditType (class XtCPreeditType)
               Tells xterm which types of preedit  (preconversion)  string  to
               display.  The default is "OverTheSpot,Root".

       printAttributes (class PrintAttributes)
               Specifies  whether  to  print graphic attributes along with the
               text.  A real DEC VTxxx  terminal  will  print  the  underline,
               highlighting codes but your printer may not handle these.

               o   "0" disables the attributes.

               o   "1"  prints  the normal set of attributes (bold, underline,
                   inverse and blink) as VT100-style control sequences.

               o   "2" prints ANSI color attributes as well.

               The default is "1".

       printFileImmediate (PrintFileImmediate)
               When the print-immediate action is invoked,  xterm  prints  the
               screen  contents  directly to a file.  Set this resource to the
               prefix of the filename (a timestamp will  be  appended  to  the
               actual name).

               The  default  is  an  empty string, i.e., "", However, when the
               print-immediate action is invoked, if the string is empty, then
               "XTerm" is used.

       printFileOnXError (PrintFileOnXError)
               If xterm exits with an X error, e.g., your connection is broken
               when the server crashes, it can be told to write  the  contents
               of  the  screen  to  a  file.   To enable the feature, set this
               resource to the prefix of the filename  (a  timestamp  will  be
               appended to the actual name).

               The  default  is an empty string, i.e., "", which disables this
               feature.  However, when the print-on-error action  is  invoked,
               if the string is empty, then "XTermError" is used.

               These error codes are handled: ERROR_XERROR, ERROR_XIOERROR and
               ERROR_ICEERROR.

       printModeImmediate (PrintModeImmediate)
               When the print-immediate action is invoked,  xterm  prints  the
               screen  contents directly to a file.  You can use the printMod-
               eImmediate resource to tell  it  to  use  escape  sequences  to
               reconstruct  the  video  attributes  and colors.  This uses the
               same values as the printAttributes resource.   The  default  is
               print-immediately action is invoked.

               o   If zero (0), then this selects the current (visible screen)
                   plus the saved lines, except if  the  alternate  screen  is
                   being  used.   In  that  case, only the alternate screen is
                   selectd.

               o   If nonzero, the bits of this  resource  value  (checked  in
                   descending order) select the range:

                   8  selects the saved lines.

                   4  selects the alternate screen.

                   2  selects the normal screen.

                   1  selects the current screen, which can be either the nor-
                      mal or alternate screen.

               The default is "9", which selects the  current  visible  screen
               plus  saved  lines,  with  no  special  case for the alternated
               screen.

       printOptsOnXError (PrintOptsOnXError)
               Specify the range of text which is printed to a file  when  the
               print-on-error action is invoked.  The resource value is inter-
               preted the same as in printOptsImmediate.

               The default is "9", which selects the  current  visible  screen
               plus  saved  lines,  with  no  special  case for the alternated
               screen.

       printerAutoClose (class PrinterAutoClose)
               If "true", xterm will close  the  printer  (a  pipe)  when  the
               application switches the printer offline with a Media Copy com-
               mand.  The default is "false".

       printerCommand (class PrinterCommand)
               Specifies a shell command to which xterm will open a pipe  when
               the first MC (Media Copy) command is initiated.  The default is
               an empty string, i.e., "".  If the resource value is  given  as
               an empty string, the printer is disabled.

       printerControlMode (class PrinterControlMode)
               Specifies  the  printer  control mode.  A "1" selects autoprint
               mode, which causes xterm to print a line from the  screen  when
               you  move  the cursor off that line with a line feed, form feed
               or vertical tab character, or an  autowrap  occurs.   Autoprint
               mode  is  overridden  by printer controller mode (a "2"), which
               causes all of the output to be directed to  the  printer.   The
               default is "0".

       printerExtent (class PrinterExtent)
               Controls  whether  a  print page function will print the entire
               If  true,  allocate  separate  color  registers  for each sixel
               device control string, e.g., for DECGCI.  If  not  true,  color
               registers  are allocated only once, when the terminal is reset.
               The default is "true".

       quietGrab (class QuietGrab)
               Controls whether the cursor is repainted  when  NotifyGrab  and
               NotifyUngrab  event  types are received during change of focus.
               The default is "false".

       renderFont (class RenderFont)
               If xterm is built with the Xft library, this  controls  whether
               the faceName resource is used.  The default is "default".

               The  resource  values  are strings, evaluated as booleans after
               startup.

               false
                    disable the feature and use the normal (bitmap) font.

               true
                    startup using the TrueType font specified by the  faceName
                    and  faceSize resource settings.  If there is no value for
                    faceName, disable the feature and use the normal  (bitmap)
                    font.

                    After  startup,  you  can  still switch to/from the bitmap
                    font using the "TrueType Fonts" menu entry.

               default
                    startup using the normal (bitmap)  font,  but  enable  the
                    "TrueType  Fonts"  menu  entry  to allow runtime switching
                    to/from TrueType fonts.

                    If there is no faceName resource set, then runtime switch-
                    ing  to  TrueType fonts is disabled.  Xterm has a separate
                    compiled-in value for faceName for the special case  where
                    renderFont is "default".  That is normally "mono".

       resizeGravity (class ResizeGravity)
               Affects the behavior when the window is resized to be taller or
               shorter.  NorthWest specifies that the top line of text on  the
               screen  stay  fixed.   If the window is made shorter, lines are
               dropped from the bottom; if the window is  made  taller,  blank
               lines  are  added  at  the bottom.  This is compatible with the
               behavior in R4.  SouthWest (the  default)  specifies  that  the
               bottom line of text on the screen stay fixed.  If the window is
               made taller, additional saved lines will be scrolled down  onto
               the  screen;  if  the  window  is  made  shorter, lines will be
               scrolled off the top of the screen, and  the  top  saved  lines
               will be dropped.

       retryInputMethod (class XtCRetryInputMethod)
               Tells  xterm  how many times to retry, in case the input-method
               o   The  command-line  -rv  option  tells  the  X  libraries to
                   reverse the foreground and background colors.  Xterm's com-
                   mand-line  options set resource values.  In particular, the
                   X Toolkit sets  the  reverseVideo  resource  when  the  -rv
                   option is used.

               o   If  the  user has also used command-line options -fg or -bg
                   to set the foreground and background colors, xterm does not
                   see  these  options  directly.   Instead,  it  examines the
                   resource values to reconstruct  the  command-line  options,
                   and  determine  which  of the colors is the user's intended
                   foreground, etc.  Their actual values are irrelevant to the
                   reverse  video  function;  some users prefer the X defaults
                   (black text on a white  background),  others  prefer  white
                   text on a black background.

               o   After  startup,  the  user  can  toggle the "Enable Reverse
                   Video" menu entry.  This exchanges the  current  foreground
                   and background colors of the VT100 widget, and repaints the
                   screen.  Because of the X resource hierarchy, the reverseV-
                   ideo resource applies to more than the VT100 widget.

               Programs  running in an xterm can also use control sequences to
               enable the VT100 reverse video mode.  These are independent  of
               the  reverseVideo resource and the menu entry.  Xterm exchanges
               the current foreground and background colors when drawing  text
               affected by these control sequences.

               Other control sequences can alter the foreground and background
               colors which are used:

               o   Programs can also use the ANSI color control  sequences  to
                   set the foreground and background colors.

               o   Extensions  to the ANSI color controls (such as 16-, 88- or
                   256-colors) are treated similarly to the ANSI control.

               o   Using other control sequences (the  "dynamic  colors"  fea-
                   ture),  a  program can change the foreground and background
                   colors.

       reverseWrap (class ReverseWrap)
               Specifies whether or not reverse-wraparound should be  enabled.
               This  corresponds  to  xterm's private mode 45.  The default is
               "false".

       rightScrollBar (class RightScrollBar)
               Specifies whether or not the scrollbar should be  displayed  on
               the right rather than the left.  The default is "false".

       saveLines (class SaveLines)
               Specifies  the  number  of  lines to save beyond the top of the
               screen when a scrollbar is turned on.  The default is "64".

               cause  the  scrollbar  to  go  to  the  bottom of the scrolling
               region.  This corresponds to xterm's private  mode  1011.   The
               default is "false".

       scrollLines (class ScrollLines)
               Specifies  the number of lines that the scroll-back and scroll-
               forw actions should use as a default.  The default value is 1.

       scrollTtyOutput (class ScrollCond)
               Specifies whether or not output to the terminal should automat-
               ically cause the scrollbar to go to the bottom of the scrolling
               region.  The default is "true".

       selectToClipboard (class SelectToClipboard)
               Tells xterm whether to use the PRIMARY or CLIPBOARD for  SELECT
               tokens  in  the selection mechanism.  The set-select action can
               change this at runtime, allowing the user to work with programs
               that  handle  only  one  of  these  mechanisms.  The default is
               "false", which tells it to use PRIMARY.

       shiftFonts (class ShiftFonts)
               Specifies whether to enable the  actions  larger-vt-font()  and
               smaller-vt-font(),  which  are  normally  bound  to the shifted
               KP_Add and KP_Subtract.  The default is "true".

       showBlinkAsBold (class ShowBlinkAsBold)
               Tells xterm whether to display text  with  blink-attribute  the
               same  as  bold.   If  xterm  has not been configured to support
               blinking text, the default  is  "true",  which  corresponds  to
               older versions of xterm, otherwise the default is "false".

       showMissingGlyphs (class ShowMissingGlyphs)
               Tells  xterm  whether to display a box outlining places where a
               character has been used that the font does not represent.   The
               default is "false".

       showWrapMarks (class ShowWrapMarks)
               For  debugging  xterm  and applications that may manipulate the
               wrapped-line flag by writing text at the right margin,  show  a
               mark  on  the right inner-border of the window.  The mark shows
               which lines have the flag set.

       signalInhibit (class SignalInhibit)
               Specifies whether or not the entries in the "Main Options" menu
               for sending signals to xterm should be disallowed.  The default
               is "false".

       sixelScrolling (class SixelScrolling)
               If true, graphics scroll up one line  at  a  time  when  sixels
               would  be  written  past  the  bottom  line on the window.  The
               default is "false".

       tekGeometry (class Geometry)
               Specifies the preferred size and position of the Tektronix win-

       tekStartup (class TekStartup)
               Specifies  whether  or  not  xterm should start up in Tektronix
               mode.  The default is "false".

       tiXtraScroll (class TiXtraScroll)
               Specifies whether xterm should scroll to a new page  when  pro-
               cessing  the ti termcap entry, i.e., the private modes 47, 1047
               or 1049.  This is only in  effect  if  titeInhibit  is  "true",
               because  the  intent  of this option is to provide a picture of
               the full-screen application's display on the scrollback without
               wiping  out the text that would be shown before the application
               was initialized.  The default for this resource is "false".

       titeInhibit (class TiteInhibit)
               Specifies whether or not xterm should remove ti and te  termcap
               entries (used to switch between alternate screens on startup of
               many screen-oriented programs) from  the  TERMCAP  string.   If
               set,  xterm  also  ignores the escape sequence to switch to the
               alternate screen.  Xterm supports terminfo in a different  way,
               supporting  composite  control sequences (also known as private
               modes) 1047, 1048 and 1049 which have the same  effect  as  the
               original 47 control sequence.  The default for this resource is
               "false".

       titleModes (class TitleModes)
               Tells xterm whether to accept or return window- and icon-labels
               in ISO-8859-1 (the default) or UTF-8.  Either can be encoded in
               hexadecimal.  The default for this resource is "0".

               Each bit (bit "0" is 1, bit "1" is 2, etc.)  corresponds to one
               of the parameters set by the title modes control sequence:

               0    Set window/icon labels using hexadecimal

               1    Query window/icon labels using hexadecimal

               2    Set  window/icon  labels  using UTF-8 (overrides utf8Title
                    resource).

               3    Query window/icon labels using UTF-8

       translations (class Translations)
               Specifies the key and button bindings  for  menus,  selections,
               "programmed  strings",  etc.   The translations resource, which
               provides much of xterm's configurability, is a feature of the X
               Toolkit Intrinsics library (Xt).  See the ACTIONS section.

       trimSelection (class TrimSelection)
               If  you  set  highlightSelection, you can see the text which is
               selected, including any trailing spaces.  Clearing  the  screen
               (or  a  line)  resets it to a state containing no spaces.  Some
               lines may contain trailing spaces when  an  application  writes
               them  to  the screen.  However, you may not wish to paste lines
               with trailing spaces.  If this resource  is  true,  xterm  will
               Tell  xterm whether to use clipping to keep from producing dots
               outside the text drawing area.  Originally used to work  around
               for overstriking effects, this is also needed to work with some
               incorrectly-sized fonts.  The default is "true".

       utf8 (class Utf8)
               This specifies whether xterm will run in UTF-8  mode.   If  you
               set  this resource, xterm also sets the wideChars resource as a
               side-effect.  The resource can be set via the menu entry "UTF-8
               Encoding".  The default is "default".

               Xterm  accepts  either  a keyword (ignoring case) or the number
               shown in parentheses:

               false (0)
                  UTF-8 mode is initially off.  The  command-line  option  +u8
                  sets the resource to this value.  Escape sequences for turn-
                  ing UTF-8 mode on/off are allowed.

               true (1)
                  UTF-8 mode is initially on.  Escape  sequences  for  turning
                  UTF-8 mode on/off are allowed.

               always (2)
                  The command-line option -u8 sets the resource to this value.
                  Escape sequences for turning UTF-8 mode on/off are ignored.

               default (3)
                  This is the default value of the resource.   It  is  changed
                  during   initialization  depending  on  whether  the  locale
                  resource was set, to false  (0)  or  always  (2).   See  the
                  locale  resource  for  additional  discussion  of  non-UTF-8
                  locales.

               If you want to set the value of utf8,  it  should  be  in  this
               range.  Other nonzero values are treated the same as "1", i.e.,
               UTF-8 mode is initially on, and escape  sequences  for  turning
               UTF-8 mode on/off are allowed.

       utf8Fonts (class Utf8Fonts)
               See  the  discussion  of  the  locale resource.  This specifies
               whether xterm will use UTF-8 fonts specified via resource  pat-
               terns  such  as  "*vt100.utf8Fonts.font" or normal (ISO-8859-1)
               fonts via patterns such as "*vt100.font".  The resource can  be
               set   via  the  menu  entry  "UTF-8  Fonts".   The  default  is
               "default".

               Xterm accepts either a keyword (ignoring case)  or  the  number
               shown in parentheses:

               false (0)
                      Use  the  ISO-8859-1  fonts.  The menu entry is enabled,
                      allowing the choice of fonts to be changed at runtime.

       utf8Latin1 (class Utf8Latin1)
               If true, allow an ISO-8859-1 normal font to be combined with an
               ISO-10646 font if the latter is given via the -fw option or its
               corresponding resource value.  The default is "false".

       utf8SelectTypes (class Utf8SelectTypes)
               Override   xterm's   default   selection   target   list   (see
               SELECT/PASTE) for selections in  wide-character  (UTF-8)  mode.
               The  default is an empty string, i.e., "", which does not over-
               ride anything.

       utf8Title (class Utf8Title)
               Applications  can  set  xterm's  title  by  writing  a  control
               sequence.   Normally  this  control  sequence follows the VT220
               convention, which encodes the string in ISO-8859-1  and  allows
               for an 8-bit string terminator.  If xterm is started in a UTF-8
               locale, it translates the ISO-8859-1 string to  UTF-8  to  work
               with the X libraries which assume the string is UTF-8.

               However, some users may wish to write a title string encoded in
               UTF-8.  The window manager is responsible  for  drawing  window
               titles.   Some window managers (not all) support UTF-8 encoding
               of window titles.  Set this resource to "true" to  allow  UTF-8
               encoded  title strings.  That cancels the translation to UTF-8,
               allowing UTF-8 strings to be displayed as is.

               This feature is available as a menu entry, since it is  related
               to  the  particular  applications you are running within xterm.
               You can also use a control  sequence  (see  the  discussion  of
               "Title  Modes"  in  the  control sequences document), to set an
               equivalent flag.  The titleModes resource sets the same  value,
               which overrides this resource.

               The default is "false".

       veryBoldColors (class VeryBoldColors)
               Specifies whether to combine video attributes with colors spec-
               ified by colorBD, colorBL, colorRV and colorUL.   The  resource
               value is the sum of values for each attribute:
                 1 for reverse,
                 2 for underline,
                 4 for bold and
                 8 for blink.

               The default is "0".

       visualBell (class VisualBell)
               Specifies whether or not a visible bell (i.e., flashing) should
               be used instead of an audible bell when Control-G is  received.
               The  default  is  "false",  which tells xterm to use an audible
               bell.

       visualBellDelay (class VisualBellDelay)
               Number of milliseconds to delay when displaying a visual  bell.
               acter  escape  sequences  while  in UTF-8 mode.  The default is
               "true", to provide support for various legacy applications.

       wideBoldFont (class WideBoldFont)
               This option specifies the font to be used for  displaying  bold
               wide  text.  By default, it will attempt to use a font twice as
               wide as the font that will be used to draw bold  text.   If  no
               double-width  font  is  found, it will improvise, by stretching
               the bold font.

       wideChars (class WideChars)
               Specifies if xterm should respond  to  control  sequences  that
               process 16-bit characters.  The default is "false".

       wideFont (class WideFont)
               This  option  specifies the font to be used for displaying wide
               text.  By default, it will attempt to use a font twice as  wide
               as  the font that will be used to draw normal text.  If no dou-
               ble-width font is found, it will improvise, by  stretching  the
               normal font.

       ximFont (class XimFont)
               This  option  specifies  the font to be used for displaying the
               preedit string in the "OverTheSpot" input method.

               In "OverTheSpot"  preedit  type,  the  preedit  (preconversion)
               string  is  displayed at the position of the cursor.  It is the
               XIM server's responsibility to display the preedit string.  The
               XIM  client  must inform the XIM server of the cursor position.
               For best results, the preedit string must be displayed  with  a
               proper  font.   Therefore,  xterm informs the XIM server of the
               proper font.  The font is be supplied  by  a  "fontset",  whose
               default  value  is "*".  This matches every font, the X library
               automatically chooses fonts with proper charsets.  The  ximFont
               resource is provided to override this default font setting.

   Scrollbar Resources
       The  following  resources  are  useful  when  specified  for the Athena
       Scrollbar widget:

       thickness (class Thickness)
               Specifies the width in pixels of the scrollbar.

       background (class Background)
               Specifies the color to use for the background of the scrollbar.

       foreground (class Foreground)
               Specifies the color to use for the foreground of the scrollbar.
               The  "thumb"  of the scrollbar is a simple checkerboard pattern
               alternating pixels for foreground and background color.

POINTER USAGE
       Once the VT102 window is created, xterm allows you to select  text  and
       copy it within the same or other windows.

   SELECTION
       The  selection  functions are invoked when the pointer buttons are used
       with no modifiers, and when they are used with the  "shift"  key.   The
       assignment  of the functions described below to keys and buttons may be
       changed through the resource database; see ACTIONS below.

       Pointer button one (usually left) is used to save  text  into  the  cut
       buffer.   Move  the  cursor to beginning of the text, and then hold the
       button down while moving the cursor  to  the  end  of  the  region  and
       releasing the button.  The selected text is highlighted and is saved in
       the global cut buffer and made the PRIMARY selection when the button is
       released.  Normally (but see the discussion of on2Clicks, etc):

       o   Double-clicking selects by words.

       o   Triple-clicking selects by lines.

       o   Quadruple-clicking goes back to characters, etc.

       Multiple-click is determined by the time from button up to button down,
       so you can change the selection unit in  the  middle  of  a  selection.
       Logical words and lines selected by double- or triple-clicking may wrap
       across more than one screen line if lines were wrapped by xterm  itself
       rather  than by the application running in the window.  If the key/but-
       ton bindings specify that an X selection is  to  be  made,  xterm  will
       leave  the selected text highlighted for as long as it is the selection
       owner.

       Pointer button two (usually middle) "types" (pastes) the text from  the
       PRIMARY  selection, if any, otherwise from the cut buffer, inserting it
       as keyboard input.
       By  cutting  and pasting pieces of text without trailing new lines, you
       can take text from several places in different windows and form a  com-
       mand  to  the  shell,  for  example,  or take output from a program and
       insert it into your favorite editor.  Since cut  buffers  are  globally
       shared  among  different  applications, you may regard each as a "file"
       whose contents you know.  The terminal emulator and other text programs
       should  be  treating  it  as  if it were a text file, i.e., the text is
       delimited by new lines.

   SCROLLING
       The scroll region displays the position and amount  of  text  currently
       showing  in  the  window  (highlighted)  relative to the amount of text
       actually saved.  As more text is saved (up to the maximum), the size of
       the highlighted area decreases.

       Clicking  button  one  with  the pointer in the scroll region moves the
       adjacent line to the top of the display window.

       Clicking button three moves the top line of the display window down  to
       the pointer position.

       Clicking  button  two moves the display to a position in the saved text
       that corresponds to the pointer's position in the scrollbar.

   TEKTRONIX POINTER
       Unlike the VT102 window, the Tektronix window does not allow the  copy-
       ing  of  text.   It does allow Tektronix GIN mode, and in this mode the
       cursor will change from an arrow to a cross.   Pressing  any  key  will
       send that key and the current coordinate of the cross cursor.  Pressing
       button one, two, or three will return the letters "l",  "m",  and  "r",
       respectively.   If  the "shift" key is pressed when a pointer button is
       pressed, the corresponding upper case letter is sent.  To distinguish a
       pointer  button  from  a key, the high bit of the character is set (but
       this is bit is normally stripped unless the terminal mode is  RAW;  see
       tty(4) for details).

SELECT/PASTE
       X  clients  provide  select and paste support by responding to requests
       conveyed by the server.

   PRIMARY
       When configured to use the primary selection, (the default)  xterm  can
       provide  the  selection  data  in  ways  which help to retain character
       encoding information as it is pasted.

       A user "selects" text on xterm, which highlights the selected text.   A
       subsequent  "paste"  to another client forwards a request to the client
       owning the selection.  If xterm owns the primary  selection,  it  makes
       the  data available in the form of one or more "selection targets".  If
       it does not own the primary selection, e.g., if it has released  it  or
       another client has asserted ownership, it relies on cut-buffers to pass
       the data.  But cut-buffers handle only ISO-8859-1  data  (officially  -
       some clients ignore the rules).


              UTF8_STRING
                   This is an XFree86 extension, which denotes that  the  data
                   is encoded in UTF-8.  When xterm is built with wide-charac-
                   ter support, it both accepts and provides this type.

              TEXT the text is in the encoding which corresponds to your  cur-
                   rent locale.

              COMPOUND_TEXT
                   this  is  a format for multiple character set data, such as
                   multi-lingual text.  It can store UTF-8 data as  a  special
                   case.

              STRING
                   This is Latin 1 (ISO-8859-1) data.

       The  middle  two (TEXT and COMPOUND_TEXT) are added if xterm is config-
       ured with the i18nSelections resource set to "true".

       UTF8_STRING is preferred (therefore first  in  the  list)  since  xterm
       stores text as Unicode data when running in wide-character mode, and no
       translation is needed.  On the other hand, TEXT and  COMPOUND_TEXT  may
       require  translation.   If  the  translation  is  incomplete, they will
       insert X's "defaultString" whose value cannot be set, and may simply be
       empty.   Xterm's defaultString resource specifies the string to use for
       incomplete translations of the UTF8_STRING.

       You can alter the types which xterm tries using the eightBitSelectTypes
       or  utf8SelectTypes  resources.  For instance, you might have some spe-
       cific locale setting which does not use UTF-8 encoding.   The  resource
       value is a comma-separated list of the selection targets, which consist
       of the names shown.  You can use the special name I18N  to  denote  the
       optional  inclusion  of  TEXT and COMPOUND_TEXT.  The names are matched
       ignoring case, and  can  be  abbreviated.   The  default  list  can  be
       expressed in several ways, e.g.,

              UTF8_STRING,I18N,STRING
              utf8,i18n,string
              u,i,s

MENUS
       Xterm  has  four  menus, named mainMenu, vtMenu, fontMenu, and tekMenu.
       Each menu pops up under the correct  combinations  of  key  and  button
       presses.  Each menu is divided into sections, separated by a horizontal
       line.  Some menu entries correspond to modes that can  be  altered.   A
       check  mark appears next to a mode that is currently active.  Selecting
       one of these modes toggles its state.  Other menu entries are commands;
       selecting one of these performs the indicated function.

       All  of  the  menu entries correspond to X actions.  In the list below,
       the menu label is shown followed by the action's name in parenthesis.

   Main Options
                     words or other sensitive data in an unsecure environment;
                     see SECURITY below (but read the limitations carefully).

              Allow SendEvents (allowsends)
                     Specifies  whether or not synthetic key and button events
                     generated using the X protocol SendEvent  request  should
                     be  interpreted  or  discarded.   This corresponds to the
                     allowSendEvents resource.

              Redraw Window (redraw)
                     Forces the X display to repaint; useful in some  environ-
                     ments.

       Commands for capturing output:

              Log to File (logging)
                     Captures  text sent to the screen in a logfile, as in the
                     -l logging option.

              Print-All Immediately
                     Invokes the print-immediate action, sending the  text  of
                     the  current  window  directly to a file, as specified by
                     the printFileImmediate, printModeImmediate and  printOpt-
                     sImmediate resources.

              Print-All on Error
                     Invokes  the  print-on-error action, which toggles a flag
                     telling xterm that if it exits with an X error,  to  send
                     the  text  of  the  current window directly to a file, as
                     specified by  the  printFileXError,  printModeXError  and
                     printOptsXError resources.

              Print Window (print)
                     Sends the text of the current window to the program given
                     in the printerCommand resource.

              Redirect to Printer (print-redir)
                     This sets the printerControlMode to 0 or 2.  You can  use
                     this to turn the printer on as if an application had sent
                     the appropriate control sequence.  It is also useful  for
                     switching  the  printer off if an application turns it on
                     without resetting the print control mode.

       Modes for setting keyboard style:

              8-Bit Controls (8-bit-control)
                     Enabled for VT220 emulation, this controls whether  xterm
                     will send 8-bit control sequences rather than using 7-bit
                     (ASCII) controls, e.g.,  sending  a  byte  in  the  range
                     128-159  rather  than  the escape character followed by a
                     second byte.  Xterm  always  interprets  both  8-bit  and
                     7-bit  control  sequences (see the document Xterm Control
                     Sequences).   This  corresponds  to  the  eightBitControl
                     resource.
                     acter sequence with the character itself preceded by ESC.
                     This corresponds to the metaSendsEscape resource.

              Delete is DEL (delete-is-del)
                     Controls whether the Delete key  on  the  editing  keypad
                     should  send  DEL  (127) or the VT220-style Remove escape
                     sequence.  This corresponds to the deleteIsDEL resource.

              Old Function-Keys (oldFunctionKeys)

              HP Function-Keys (hpFunctionKeys)

              SCO Function-Keys (scoFunctionKeys)

              Sun Function-Keys (sunFunctionKeys)

              VT220 Keyboard (sunKeyboard)
                     These act as a radio-button, selecting one style for  the
                     keyboard   layout.   It  corresponds  to  more  than  one
                     resource setting: sunKeyboard, sunFunctionKeys,  scoFunc-
                     tionKeys and hpFunctionKeys ."

       Commands for process signalling:

              Send STOP Signal (suspend)

              Send CONT Signal (continue)

              Send INT Signal (interrupt)

              Send HUP Signal (hangup)

              Send TERM Signal (terminate)

              Send KILL Signal (kill)
                     These  send the SIGTSTP, SIGCONT, SIGINT, SIGHUP, SIGTERM
                     and SIGKILL signals respectively, to the process group of
                     the process running under xterm (usually the shell).  The
                     SIGCONT function is especially useful  if  the  user  has
                     accidentally typed CTRL-Z, suspending the process.

              Quit (quit)
                     Stop  processing  X  events  except  to support the -hold
                     option, and then send a SIGHUP signal to the the  process
                     group  of  the  process  running under xterm (usually the
                     shell).

   VT Options
       The vtMenu sets various modes in the VT102 emulation, and is popped  up
       when  the "control" key and pointer button two are pressed in the VT102
       window.

       VT102/VT220 Modes:

              Enable Auto Wraparound (autowrap)
                     Enable (or disable) auto-wraparound.  This corresponds to
                     the -aw option and the autoWrap resource.

              Enable Reverse Wraparound (reversewrap)
                     Enable (or disable) reverse wraparound.  This corresponds
                     to the -rw option and the reverseWrap resource.

              Enable Auto Linefeed (autolinefeed)
                     Enable (or disable) auto-linefeed.  This is the VT102 NEL
                     function, which causes the emulator to  emit  a  linefeed
                     after  each  carriage  return.  There is no corresponding
                     command-line option or resource setting.

              Enable Application Cursor Keys (appcursor)
                     Enable (or disable) application cursor keys.  This corre-
                     sponds  to  the  appcursorDefault  resource.  There is no
                     corresponding command-line option.

              Enable Application Keypad (appkeypad)
                     Enable (or disable) application keypad keys.  This corre-
                     sponds  to  the  appkeypadDefault  resource.  There is no
                     corresponding command-line option.

              Scroll to Bottom on Key Press (scrollkey)
                     Enable (or  disable)  scrolling  to  the  bottom  of  the
                     scrolling  region on a keypress.  This corresponds to the
                     -sk option and the scrollKey resource.

                     As a special case, the XON /  XOFF  keys  (control/S  and
                     control/Q) are ignored.

              Scroll to Bottom on Tty Output (scrollttyoutput)
                     Enable  (or  disable)  scrolling  to  the  bottom  of the
                     scrolling region on output to the terminal.  This  corre-
                     sponds   to   the  -si  option  and  the  scrollTtyOutput
                     resource.

              Allow 80/132 Column Switching (allow132)
                     Enable (or disable) switching between 80 and 132 columns.
                     This   corresponds  to  the  -132  option  and  the  c132
                     resource.

              Keep Selection (keepSelection)
                     Tell xterm whether to disown the selection when it  stops
                     highlighting  it,  e.g., when an application modifies the
                     display so that it no longer matches the text  which  has
                     been  highlighted.  As long as xterm continues to own the
                     selection, it can provide the corresponding text to other
                     clients  via  cut/paste.  This corresponds to the keepSe-
                     lection resource.  There is no corresponding command-line
                     option.

              Select to Clipboard (selectToClipboard)
                     Enable (or disable) Urgency window manager hint when Con-
                     trol-G is received.  This corresponds to the bellIsUrgent
                     resource.

              Enable Pop on Bell (poponbell)
                     Enable  (or disable) raising of the window when Control-G
                     is received.  This corresponds to the -pop option and the
                     popOnBell resource.

              Enable Blinking Cursor (cursorblink)
                     Enable  (or  disable)  the blinking-cursor feature.  This
                     corresponds  to  the  -bc  option  and  the   cursorBlink
                     resource.  There is also an escape sequence (see the doc-
                     ument Xterm Control Sequences).  The menu entry  and  the
                     escape  sequence  states  are XOR'd: if both are enabled,
                     the cursor will not blink, if only one  is  enabled,  the
                     cursor will blink.

              Enable Alternate Screen Switching (titeInhibit)
                     Enable  (or  disable)  switching  between  the normal and
                     alternate screens.  This corresponds to  the  titeInhibit
                     resource.  There is no corresponding command-line option.

              Enable Active Icon (activeicon)
                     Enable (or disable) the active-icon feature.  This corre-
                     sponds to the -ai option and the activeIcon resource.

              Sixel Scrolling (sixelScrolling)
                     When enabled, sixel graphics are positioned at  the  cur-
                     rent text cursor location, scroll the image vertically if
                     larger than the screen, and leave the text  cursor  after
                     the  image  when  returning to text mode.  When disabled,
                     sixel graphics are positioned at the upper  left  of  the
                     screen,  are cropped to fit the screen, and do not affect
                     the text cursor location (this  is  the  default).   This
                     corresponds  to the sixelScrolling resource.  There is no
                     corresponding command-line option.

              Private Color Registers (privateColorRegisters)
                     When enabled, each graphic image uses a separate  set  of
                     color  registers,  so  that  it essentially has a private
                     palette (this is the default).  If it  is  not  set,  all
                     graphics  images share a common set of registers which is
                     how sixel and ReGIS graphics worked on  actual  hardware.
                     The  default is likely a more useful mode on modern True-
                     Color hardware.  This corresponds to the privateColorReg-
                     isters  resource.  There is no corresponding command-line
                     option.

       VT102/VT220 Commands:

              Do Soft Reset (softreset)
                     Reset scroll regions.  This can be convenient  when  some
                     program  has  left  the  scroll  regions  set incorrectly

              Reset and Clear Saved Lines (clearsavedlines)
                     Perform a full reset, and also clear the saved lines.

       Commands for setting the current screen:

              Show Tek Window (tekshow)
                     When enabled, pops the Tektronix 4014 window up (makes it
                     visible).   When  disabled, hides the Tektronix 4014 win-
                     dow.

              Switch to Tek Mode (tekmode)
                     When enabled, pops the Tektronix 4014 window up if it  is
                     not  already  visible,  and  switches the input stream to
                     that window.  When disabled,  hides  the  Tektronix  4014
                     window and switches input back to the VTxxx window.

              Hide VT Window (vthide)
                     When enabled, hides the VTxxx window, shows the Tektronix
                     4014 window if it was not already  visible  and  switches
                     the  input  stream  to that window.  When disabled, shows
                     the VTxxx window, and switches the input stream  to  that
                     window.

              Show Alternate Screen (altscreen)
                     When enabled, shows the alternate screen.  When disabled,
                     shows the normal screen.  Note that the normal screen may
                     have saved lines; the alternate screen does not.

   VT Fonts
       The  fontMenu  pops  up  when when the "control" key and pointer button
       three are pressed in a window.  It sets the font used in the VT102 win-
       dow, or modifies the way the font is specified or displayed.  There are
       several sections.

       The first section allows you to select the font from a set of  alterna-
       tives:

              Default (fontdefault)
                     Set  the  font  to  the  default, i.e., that given by the
                     *VT100.font resource.

              Unreadable (font1)
                     Set the font to that given by the *VT100.font1 resource.

              Tiny (font2)
                     Set the font to that given by the *VT100.font2 resource.

              Small (font3)
                     Set the font to that given by the *VT100.font3 resource.

              Medium (font4)
                     Set the font to that given by the *VT100.font4 resource.

                     This allows you to set the  font  specified  the  current
                     selection  as  a  font  name (if the PRIMARY selection is
                     owned).

       The second section allows you to modify the way it is displayed:

              Bold Fonts
                     This is  normally  checked  (enabled).   When  unchecked,
                     xterm  will  not use bold fonts.  The setting corresponds
                     to the allowBoldFonts resource.

              Line-Drawing Characters (font-linedrawing)
                     When set, tells xterm to draw its own line-drawing  char-
                     acters.   Otherwise  it  relies  on  the  font containing
                     these.  Compare to the forceBoxChars resource.

              Packed Font (font-packed)
                     When set, tells xterm to use the minimum glyph-width from
                     a font when displaying characters.  Use the maximum width
                     (unchecked) to help display proportional fonts.   Compare
                     to the forcePackedFont resource.

              Doublesized Characters (font-doublesize)
                     When set, xterm may ask the font server to produce scaled
                     versions of the normal font, for VT102 double-size  char-
                     acters.

       The third section allows you to modify the way it is specified:

              TrueType Fonts (render-font)
                     If  the  renderFont and corresponding resources were set,
                     this is a further control whether xterm will actually use
                     the Xft library calls to obtain a font.

              UTF-8 Encoding (utf8-mode)
                     This  controls  whether  xterm  uses  UTF-8  encoding  of
                     input/output.  It is  useful  for  temporarily  switching
                     xterm  to display text from an application which does not
                     follow the locale settings.  It corresponds to  the  utf8
                     resource.

              UTF-8 Fonts (utf8-fonts)
                     This controls whether xterm uses UTF-8 fonts for display.
                     It is useful for temporarily switching xterm  to  display
                     text from an application which does not follow the locale
                     settings.  It combines the utf8 and utf8Fonts resources.

              UTF-8 Titles (utf8-titles)
                     This controls whether xterm accepts  UTF-8  encoding  for
                     title control sequences.  It corresponds to the utf8Fonts
                     resource.

                     Initially the checkmark is set according to both the utf8
                     and  utf8Fonts  resource values.  If the latter is set to

              The fourth section allows you to enable or disable special oper-
              ations  which  can  be controlled by writing escape sequences to
              the terminal.  These are disabled if the SendEvents  feature  is
              enabled:

              Allow Color Ops (allow-font-ops)
                     This  corresponds  to the allowColorOps resource.  Enable
                     or disable control sequences that set/query the colors.

              Allow Font Ops (allow-font-ops)
                     This corresponds to the allowFontOps resource.  Enable or
                     disable control sequences that set/query the font.

              Allow Tcap Ops (allow-tcap-ops)
                     Enable or disable control sequences that query the termi-
                     nal's notion of its function-key strings, as  termcap  or
                     terminfo  capabilities.   This corresponds to the allowT-
                     capOps resource.

              Allow Title Ops (allow-title-ops)
                     Enable or disable control sequences that modify the  win-
                     dow title or icon name.  This corresponds to the allowTi-
                     tleOps resource.

              Allow Window Ops (allow-window-ops)
                     Enable or disable extended window control  sequences  (as
                     used  in dtterm).  This corresponds to the allowWindowOps
                     resource.

   TEK Options
       The tekMenu sets various modes  in  the  Tektronix  emulation,  and  is
       popped  up when the "control" key and pointer button two are pressed in
       the Tektronix window.  The current font size is checked  in  the  modes
       section of the menu.

              Large Characters (tektextlarge)

              #2 Size Characters (tektext2)

              #3 Size Characters (tektext3)

              Small Characters (tektextsmall)

       Commands:

              PAGE (tekpage)
                     Clear the Tektronix window.

           mechanism to control access to the server (see xhost(1)),  then  if
           you  enable access for a host and other users are also permitted to
           run clients on that same host, it is possible that someone can  run
           an  application  which uses the basic services of the X protocol to
           snoop on your activities, potentially  capturing  a  transcript  of
           everything you type at the keyboard.

       o   Any process which has access to your X display can manipulate it in
           ways that you might not anticipate, even redirecting your  keyboard
           to  itself  and sending events to your application's windows.  This
           is true even with the "magic cookie" authorization  scheme.   While
           the allowSendEvents provides some protection against rogue applica-
           tions tampering with your programs, guarding against a  snooper  is
           harder.

       o   The  X input extension for instance allows an application to bypass
           all of the other (limited)  authorization  and  security  features,
           including the GrabKeyboard protocol.

       o   The  possibility  of an application spying on your keystrokes is of
           particular concern when you want to type in  a  password  or  other
           sensitive data.  The best solution to this problem is to use a bet-
           ter authorization mechanism than is provided by X.

       Subject to all of these caveats, a simple mechanism exists for protect-
       ing keyboard input in xterm.

       The  xterm  menu  (see  MENUS  above)  contains a Secure Keyboard entry
       which, when enabled, attempts to ensure  that  all  keyboard  input  is
       directed only to xterm (using the GrabKeyboard protocol request).  When
       an application prompts you for a password (or  other  sensitive  data),
       you  can  enable  Secure Keyboard using the menu, type in the data, and
       then disable Secure Keyboard using the menu again.

       o   This ensures that you know which  window  is  accepting  your  key-
           strokes.

       o   It  cannot  ensure that there are no processes which have access to
           your X display that might be observing the keystrokes as well.

       Only one X client at a time can grab the keyboard, so when you  attempt
       to  enable  Secure  Keyboard  it may fail.  In this case, the bell will
       sound.  If the Secure Keyboard succeeds, the foreground and  background
       colors will be exchanged (as if you selected the Reverse Video entry in
       the Modes menu); they will be exchanged  again  when  you  exit  secure
       mode.   If the colors do not switch, then you should be very suspicious
       that you are being spoofed.  If the application you  are  running  dis-
       plays  a  prompt  before asking for the password, it is safest to enter
       secure mode before the prompt gets displayed, and to make sure that the
       prompt  gets  displayed  correctly (in the new colors), to minimize the
       probability of spoofing.  You can also bring up the menu again and make
       sure that a check mark appears next to the entry.

       Secure  Keyboard mode will be disabled automatically if your xterm win-
       should filenames be selected as a whole or only the separate subnames),
       the default mapping can be overridden through the use of the  charClass
       (class CharClass) resource.

       This resource is a series of comma-separated of range:value pairs.  The
       range is either a single number or low-high in the range of 0 to 65535,
       corresponding  to  the  code for the character or characters to be set.
       The value is arbitrary, although the default table uses  the  character
       number  of the first character occurring in the set.  When not in UTF-8
       mode, only the first 256 bytes of this table will be used.

       The default table starts as follows -

           static int charClass[256] = {

              For example, the string  "33:48,37:48,45-47:48,38:48"  indicates
              that  the  exclamation  mark, percent sign, dash, period, slash,
              and ampersand characters should be treated the same way as char-
              acters  and  numbers.   This  is  useful for cutting and pasting
              electronic mailing addresses and filenames.

KEY BINDINGS
       It is possible to rebind keys  (or  sequences  of  keys)  to  arbitrary
       strings for input, by changing the translations resources for the vt100
       or tek4014 widgets.  Changing  the  translations  resource  for  events
       other than key and button events is not expected, and will cause unpre-
       dictable behavior.

   ACTIONS
       The following actions are provided for use within the vt100 or  tek4014
       translations resources:

       allow-color-ops(on/off/toggle)
               This  action sets, unsets or toggles the allowColorOps resource
               and is also invoked by the allow-color-ops entry in fontMenu.

       allow-font-ops(on/off/toggle)
               This action sets, unsets or toggles the  allowFontOps  resource
               and is also invoked by the allow-font-ops entry in fontMenu.

       allow-send-events(on/off/toggle)
               This   action  sets,  unsets  or  toggles  the  allowSendEvents
               resource and is also invoked by the allowsends entry  in  main-
               Menu.

       allow-tcap-ops(on/off/toggle)
               This  action  sets, unsets or toggles the allowTcapOps resource
               and is also invoked by the allow-tcap-ops entry in fontMenu.

       allow-title-ops(on/off/toggle)
               This action sets, unsets or toggles the allowTitleOps  resource
               and is also invoked by the allow-title-ops entry in fontMenu.

       allow-window-ops(on/off/toggle)
               This action sets, unsets or toggles the allowWindowOps resource
               and is also invoked by the allow-window-ops entry in fontMenu.
               is identical to a hardware reset (RIS) control sequence.

       copy-selection(destname [, ...])
               This action puts the currently selected text into  all  of  the
               selections or cutbuffers specified by destname.  Unlike select-
               end, it does not send a mouse position or otherwise modify  the
               internal selection state.

       create-menu(m/v/f/t)
               This  action  creates one of the menus used by xterm, if it has
               not been previously created.  The parameter values are the menu
               names: mainMenu, vtMenu, fontMenu, tekMenu, respectively.

       dabbrev-expand()
               Expands  the  word  before cursor by searching in the preceding
               text on the screen and  in  the  scrollback  buffer  for  words
               starting  with  that  abbreviation.  Repeating dabbrev-expand()
               several times in sequence searches for an alternative expansion
               by looking farther back.  Lack of more matches is signaled by a
               beep().  Attempts to expand an empty word (i.e., when cursor is
               preceded  by  a  space)  yield successively all previous words.
               Consecutive identical expansions are ignored.  The word here is
               defined  as a sequence of non-whitespace characters.  This fea-
               ture partially emulates the behavior of "dynamic  abbreviation"
               expansion  in  Emacs  (bound there to M-/).  Here is a resource
               setting for xterm which will do the same thing:

                   *VT100*translations:    #override \n\
                           Meta <KeyPress> /:dabbrev-expand()

       deiconify()
               Changes the window state back to normal, if it was iconified.

       delete-is-del()
               This action toggles the state of the deleteIsDEL resource.

       dired-button()
               Handles a button event (other than press and release) by  echo-
               ing  the  event's position (i.e., character line and column) in
               the following format:

                       ^X ESC G <line+" "> <col+" ">

       fullscreen(on/off/toggle)
               This action sets, unsets or toggles the fullscreen resource.

       iconify()
               Iconifies the window.

       hard-reset()
               This action resets the scrolling region, tabs, window size, and
               cursor keys and clears the screen.  It is also invoked from the
               hardreset entry in vtMenu.

               depends  on  the  value of the altSendsEscape and the metaSend-
               sEscape and the eightBitInput resources.   The  metaSendsEscape
               resource is tested first.  See the eightBitInput resource for a
               full discussion.

               The term "eight-bit" is misleading: xterm checks if the key  is
               in  the range 128 to 255 (the eighth bit is set).  If the value
               is in that range, depending on the resource values,  xterm  may
               then do one of the following:

               o   add 128 to the value, setting its eighth bit,

               o   send an ESC byte before the key, or

               o   send the key unaltered.

       exec-formatted(format, sourcename [, ...])
               Execute  an  external  command, using the current selection for
               part of the command's parameters.  The first parameter,  format
               gives  the  basic  command.   Succeeding parameters specify the
               selection source as in insert-selection.

               The format parameter allows these substitutions:

               %%   inserts a "%".

               %P   the screen-position at the beginning  of  the  highlighted
                    region,  as  a  semicolon-separated pair of integers using
                    the values that the CUP control sequence would use.

               %p   the screen-position after the beginning of the highlighted
                    region, using the same convention as "%P".

               %S   the length of the string that "%s" would insert.

               %s   the content of the selection, unmodified.

               %T   the length of the string that "%t" would insert.

               %t   the selection, trimmed of leading/trailing whitespace, and
                    newlines changed to single spaces.

               %V   the video attributes at the beginning of  the  highlighted
                    region,  as  a  semicolon-separated list of integers using
                    the values that the SGR control sequence would use.

               %v   the video attributes after  the  end  of  the  highlighted
                    region, using the same convention as "%V".

               After constructing the command-string, xterm forks a subprocess
               and executes the  command,  which  completes  independently  of
               xterm.

       exec-selectable(format, onClicks)
       insert-selectable(format, onClicks)
               Insert data copied  from  the  screen,  formatted.   The  first
               parameter,  format  gives the template for the data as in exec-
               formatted.  The second parameter specifies the method for copy-
               ing the data as in the onClicks resource.

       insert-selection(sourcename [, ...])
               This  action  inserts the string found in the selection or cut-
               buffer indicated by sourcename.  Sources  are  checked  in  the
               order  given  (case  is  significant) until one is found.  Com-
               monly-used selections include: PRIMARY,  SECONDARY,  and  CLIP-
               BOARD.   Cut  buffers  are  typically named CUT_BUFFER0 through
               CUT_BUFFER7.

       insert-seven-bit()
               This action is a synonym for insert() The term  "seven-bit"  is
               misleading:  it only implies that xterm does not try to add 128
               to the key's value as in insert-eight-bit().

       interpret(control-sequence)
               Interpret the given control  sequence  locally,  i.e.,  without
               passing  it  to  the host.  This works by inserting the control
               sequence at the front of the input buffer.  Use "\"  to  escape
               octal  digits  in  the  string.  Xt does not allow you to put a
               null character (i.e., "\000") in the string.

       keymap(name)
               This action dynamically defines a new translation  table  whose
               resource  name is name with the suffix Keymap (case is signifi-
               cant).  The name None restores the original translation table.

       larger-vt-font()
               Set the font to the next larger one, based on the  font  dimen-
               sions.  See also set-vt-font().

       load-vt-fonts(name[,class])
               Load fontnames from the given subresource name and class.  That
               is, load the "*VT100.name.font", resource as "*VT100.font" etc.
               If no name is given, the original set of fontnames is restored.

               Unlike  set-vt-font(),  this  does  not  affect the escape- and
               select-fonts, since those are not based on resource values.  It
               does  affect  the  fonts  loosely organized under the "Default"
               menu entry, including font, boldFont,  wideFont  and  wideBold-
               Font.

       maximize()

               This  action  displays  the  specified popup menu.  Valid names
                    no form feed will be sent at the  end  of  the  last  line
                    printed (i.e., printerFormFeed is ``false'').

               FormFeed
                    a  form  feed  will  be  sent  at the end of the last line
                    printed (i.e., printerFormFeed is ``true'').

               noNewLine
                    no newline will be sent  at  the  end  of  the  last  line
                    printed,  and  wrapped  lines  will  be combined into long
                    lines (i.e., printerNewLine is ``false'').

               NewLine
                    a newline will be  sent  at  the  end  of  the  last  line
                    printed,  and  each line will be limited (by adding a new-
                    line)  to  the  screen  width  (i.e.,  printerNewLine   is
                    ``true'').

               noAttrs
                    the  page  is  printed  without attributes (i.e., printAt-
                    tributes is ``0'').

               monoAttrs
                    the page is printed  with  monochrome  (vt220)  attributes
                    (i.e., printAttributes is ``1'').

               colorAttrs
                    the  page  is  printed  with  ANSI color attributes (i.e.,
                    printAttributes is ``2'').

       print-everything(printer-flags)
               This action sends the entire text history, in addition  to  the
               text currently visible, to the program given in the printerCom-
               mand resource.  It allows the same optional parameters  as  the
               print  action.  With a suitable printer command, the action can
               be used to load the text history in an editor.

       print-immediate()
               Sends the text of the current window directly  to  a  file,  as
               specified  by  the  printFileImmediate,  printModeImmediate and
               printOptsImmediate resources.

       print-on-error()
               Toggles a flag telling xterm that if it exits with an X  error,
               to  send  the text of the current window directly to a file, as
               specified by the printFileXError, printModeXError and printOpt-
               sXError resources.

       print-redir()
               This  action  toggles  the  printerControlMode between 0 and 2.
               The corresponding popup menu entry is useful for switching  the
               printer off if you happen to change your mind after deciding to
               print random binary files on the terminal.


       restore()
               Restores the window to the size before it was last maximized.

       scroll-back(count [,units [,mouse] ])
               This  action scrolls the text window backward so that text that
               had previously scrolled off the top of the screen is now  visi-
               ble.

               The  count argument indicates the number of units (which may be
               page, halfpage, pixel, or line) by which to scroll.

               An adjustment can be specified for these values by appending  a
               "+" or "-" sign followed by a number, e.g., page-2 to specify 2
               lines less than a page.

               If the third parameter mouse is given, the  action  is  ignored
               when mouse reporting is enabled.

               have a modern version of the process filesystem, e.g., "/proc",
               which xterm can read.

               Use the "cwd" process entry, e.g.,  /proc/12345/cwd  to  obtain
               the  working  directory  of the process which is running in the
               current xterm.

               On  systems  which  have  the  "exe"   process   entry,   e.g.,
               /proc/12345/exe,  use  this  to  obtain  the actual executable.
               Otherwise, use the $PATH variable to find xterm.

       string(string)
               This action inserts the specified text string as if it had been
               typed.  Quotation is necessary if the  string  contains  white-
               space  or  non-alphanumeric characters.  If the string argument
               begins with the characters "0x", it is  interpreted  as  a  hex
               character constant.

       tek-copy()
               This  action  copies the escape codes used to generate the cur-
               rent window contents to a file in the current directory  begin-
               ning  with  the name COPY.  It is also invoked from the tekcopy
               entry in tekMenu.

       tek-page()
               This action clears the Tektronix window.  It is also invoked by
               the tekpage entry in tekMenu.

       tek-reset()
               This action resets the Tektronix window.  It is also invoked by
               the tekreset entry in tekMenu.

       vi-button()
               Handles a button event (other than press and release) by  echo-
               ing a control sequence computed from the event's line number in
               the screen relative to the current line:

                       ESC ^P
               or
                       ESC ^N

               according to whether the event is before, or after the  current
               line,  respectively.   The ^N (or ^P) is repeated once for each
               line that the event differs from the current line.  The control
               sequence  is  omitted  altogether if the button event is on the
               current line.

       visual-bell()
               This action flashes the window quickly.

       The Tektronix window also has the following action:

       gin-press(l/L/m/M/r/R)
               This action sends the indicated graphics input code.

   DEFAULT KEY BINDINGS
       The default bindings in the VT102 window use the SELECT token, which is
       set by the selectToClipboard resource:

                     Shift <KeyPress> Prior:scroll-back(1,halfpage) \n\
                      Shift <KeyPress> Next:scroll-forw(1,halfpage) \n\
                    Shift <KeyPress> Select:select-cursor-start() \
                                            select-cursor-end(SELECT, CUT_BUFFER0) \n\
                    Shift <KeyPress> Insert:insert-selection(SELECT, CUT_BUFFER0) \n\
                            Alt <Key>Return:fullscreen() \n\

                           !Ctrl <Btn2Down>:popup-menu(vtMenu) \n\
                      !Lock Ctrl <Btn2Down>:popup-menu(vtMenu) \n\
            !Lock Ctrl @Num_Lock <Btn2Down>:popup-menu(vtMenu) \n\
                ! @Num_Lock Ctrl <Btn2Down>:popup-menu(vtMenu) \n\
                     ~Ctrl ~Meta <Btn2Down>:ignore() \n\
                            Meta <Btn2Down>:clear-saved-lines() \n\
                       ~Ctrl ~Meta <Btn2Up>:insert-selection(SELECT, CUT_BUFFER0) \n\
                           !Ctrl <Btn3Down>:popup-menu(fontMenu) \n\
                      !Lock Ctrl <Btn3Down>:popup-menu(fontMenu) \n\
            !Lock Ctrl @Num_Lock <Btn3Down>:popup-menu(fontMenu) \n\
                ! @Num_Lock Ctrl <Btn3Down>:popup-menu(fontMenu) \n\
                     ~Ctrl ~Meta <Btn3Down>:start-extend() \n\
                         ~Meta <Btn3Motion>:select-extend() \n\
                            Ctrl <Btn4Down>:scroll-back(1,halfpage,m) \n\
                       Lock Ctrl <Btn4Down>:scroll-back(1,halfpage,m) \n\
             Lock @Num_Lock Ctrl <Btn4Down>:scroll-back(1,halfpage,m) \n\
                  @Num_Lock Ctrl <Btn4Down>:scroll-back(1,halfpage,m) \n\
                                 <Btn4Down>:scroll-back(5,line,m)     \n\
                            Ctrl <Btn5Down>:scroll-forw(1,halfpage,m) \n\
                       Lock Ctrl <Btn5Down>:scroll-forw(1,halfpage,m) \n\
             Lock @Num_Lock Ctrl <Btn5Down>:scroll-forw(1,halfpage,m) \n\
                  @Num_Lock Ctrl <Btn5Down>:scroll-forw(1,halfpage,m) \n\
                                 <Btn5Down>:scroll-forw(5,line,m)     \n\
                                    <BtnUp>:select-end(SELECT, CUT_BUFFER0) \n\
                                  <BtnDown>:ignore()

       The  default  bindings  for  the scrollbar widget are separate from the
       VT100 widget:

                                 <Btn5Down>: StartScroll(Forward) \n\
                                 <Btn1Down>: StartScroll(Forward) \n\
                                 <Btn2Down>: StartScroll(Continuous) MoveThumb() NotifyThumb() \n\
                                 <Btn3Down>: StartScroll(Backward) \n\
                                 <Btn4Down>: StartScroll(Backward) \n\
                                 <Btn2Motion>: MoveThumb() NotifyThumb() \n\
                                 <BtnUp>:    NotifyScroll(Proportional) EndScroll()

       The default bindings in the Tektronix window are:

                            ~Meta<KeyPress>: insert-seven-bit() \n\
                             Meta<KeyPress>: insert-eight-bit() \n\
                           !Ctrl <Btn1Down>: popup-menu(mainMenu) \n\
                      !Lock Ctrl <Btn1Down>: popup-menu(mainMenu) \n\
            !Lock Ctrl @Num_Lock <Btn1Down>: popup-menu(mainMenu) \n\
                 !Ctrl @Num_Lock <Btn1Down>: popup-menu(mainMenu) \n\
                           !Ctrl <Btn2Down>: popup-menu(tekMenu) \n\
                      !Lock Ctrl <Btn2Down>: popup-menu(tekMenu) \n\
            !Lock Ctrl @Num_Lock <Btn2Down>: popup-menu(tekMenu) \n\
                 !Ctrl @Num_Lock <Btn2Down>: popup-menu(tekMenu) \n\
                      Shift ~Meta<Btn1Down>: gin-press(L) \n\
                            ~Meta<Btn1Down>: gin-press(l) \n\
                      Shift ~Meta<Btn2Down>: gin-press(M) \n\
                            ~Meta<Btn2Down>: gin-press(m) \n\
                      Shift ~Meta<Btn3Down>: gin-press(R) \n\

           *VT100*translations:    #override \n\
               ~Shift~Ctrl<Btn2Up>: insert-selection(PRIMARY, CUT_BUFFER0) \n\
               Shift~Ctrl<Btn2Up>:  insert-selection(CLIPBOARD, CUT_BUFFER1) \n\
               ~Shift<BtnUp>:       select-end(PRIMARY, CUT_BUFFER0) \n\
               Shift<BtnUp>:        select-end(CLIPBOARD, CUT_BUFFER1)

       Below is a sample of how the keymap() action is  used  to  add  special
       keys for entering commonly-typed works:

           *VT100.Translations: #override <Key>F13: keymap(dbx)
           *VT100.dbxKeymap.translations: \
                   <Key>F14: keymap(None) \n\
                   <Key>F17: string("next") string(0x0d) \n\
                   <Key>F18: string("step") string(0x0d) \n\
                   <Key>F19: string("continue") string(0x0d) \n\
                   <Key>F20: string("print ") insert-selection(PRIMARY, CUT_BUFFER0)

       Some  people  prefer  using  the  left  pointer button for dragging the
       scrollbar thumb.  That  can  be  setup  by  altering  the  translations
       resource, e.g.,

           *VT100.scrollbar.translations:                                #override \n\
                   <Btn5Down>:                                           StartScroll(Forward) \n\
                   <Btn1Down>:                                           StartScroll(Continuous) MoveThumb() NotifyThumb() \n\
                   <Btn4Down>:                                           StartScroll(Backward) \n\
                   <Btn1Motion>:                                         MoveThumb() NotifyThumb() \n\
                   <BtnUp>:  NotifyScroll(Proportional) EndScroll()

CONTROL SEQUENCES AND KEYBOARD
       The  Xterm Control Sequences document lists the control sequences which
       an application can send xterm to make it  perform  various  operations.
       Most  of these operations are standardized, from either the DEC or Tek-
       tronix terminals, or from more widely used standards such as ISO-6429.

ENVIRONMENT
       Xterm sets several environment variables:

       DISPLAY
            is the display name, pointing to the X server (see  DISPLAY  NAMES
            in X(7)).

       TERM is  set  according  to the termcap (or terminfo) entry which it is
            using as a reference.

       WINDOWID
            is set to the X window id number of the xterm window.

       XTERM_FILTER
            is set if a locale-filter is used.  The value is the  pathname  of
            the filter.

       XTERM_LOCALE
            shows  the  locale which was used by xterm on startup.  Some shell
            initialization scripts may set a different locale.

       Depending on your system configuration, xterm may also set the  follow-
       ing:

       COLUMNS
            the width of the xterm in characters (cf: "stty columns").

       HOME when xterm is configured to update utmp.

       LINES
            the height of the xterm in characters (cf: "stty rows").

       LOGNAME
            when xterm is configured to update utmp.

       SHELL
            when  xterm  is  configured to update utmp.  It is also set if you
            provide the shell name as the optional parameter.

       TERMCAP
            the contents of the termcap entry  corresponding  to  $TERM,  with
            lines  and  columns  values substituted for the actual size window
            you have created.

       TERMINFO
            may be defined to a nonstandard location in the configure script.

FILES
       The actual pathnames given may differ on your system.

       /var/run/utmp
            the system logfile, which records user logins.

       /var/log/wtmp
            the system logfile, which records user logins and logouts.

       /etc/X11/app-defaults/XTerm
            the xterm default application resources.

       /etc/X11/app-defaults/XTerm-color
            the xterm color application resources.  If your  display  supports
            color, use this
                      *customization: -color
            in  your  .Xdefaults  file to automatically use this resource file
            rather than /etc/X11/app-defaults/XTerm.  If you do not  do  this,
            xterm uses its compiled-in default resource settings for colors.

       /usr/share/pixmaps
            the directory in which xterm's pixmap icon files are installed.

ERROR MESSAGES
       Most of the fatal error messages from xterm use the following format:
              xterm: Error XXX, errno YYY: ZZZ
       The  XXX  codes  (which  are used by xterm as its exit-code) are listed

BUGS
       Large  pastes do not work on some systems.  This is not a bug in xterm;
       it is a bug in the pseudo terminal  driver  of  those  systems.   xterm
       feeds large pastes to the pty only as fast as the pty will accept data,
       but some pty drivers do not return enough information to  know  if  the
       write has succeeded.

       When  connected to an input method, it is possible for xterm to hang if
       the XIM server is suspended or killed.
