xterm


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

DESCRIPTION
       The  xterm  program is a terminal emulator for the X Window System.  It
       provides DEC VT102/VT220 (VTxxx) and Tektronix 4014  compatible  termi-
       nals  for  programs that cannot use the window system directly.  If the
       underlying operating system  supports  terminal  resizing  capabilities
       (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,"
       "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 decTerminalID
       resource.  (The "TERMCAP" environment variable is not set if  xterm  is
       linked  against  a terminfo library, since the requisite information 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
       second when the COPY was performed (the file is created in  the  direc-

       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 names an executable file,  xterm  uses  that
       instead.   The parameter must be an absolute path, or name a file found
       on the user's PATH (and thereby construct an absolute  path).   The  -e
               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".

               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
               executed  if  neither  -T nor -n are given on the command line.
               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
               This option indicates that xterm should ask the window  manager
               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
               variable.
               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-
               sponds to the locale resource.

               The actual list of encodings which are supported is  determined
               by luit.  Consult the luit manual page for further details.

               See  also the discussion of the -u8 option which supports UTF-8
               locales.


       -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 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.

       -mc milliseconds
               This option specifies  the  maximum  time  between  multi-click
               selections.

       -mesg   Turn  off the messages resource, i.e., disallow write access to
               the terminal.

       +mesg   Turn on the messages resource, i.e., allow write access to  the
               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
               network  latencies  are  very high and is typically useful when
               running across a very large internet or many gateways.

       +s      This option indicates that xterm should scroll synchronously.

       -samename
               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

       +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.

       -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.

       +sm     This option indicates that xterm should not set up session man-
               ager callbacks.

       -sp     This option indicates that Sun/PC keyboard should  be  assumed,
               providing  mapping  for  keypad "+' to ",', and CTRL-F1 to F13,
               CTRL-F2 to F14, etc.

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

       -t      This  option  indicates  that  xterm  should start in Tektronix
               mode, rather than in VT102 mode.   Switching  between  the  two

       +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, and
               vt220 (the "vt" is optional).  The  default  is  "vt100".   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.

       +u8     This option resets the utf8 resource.

       -uc     This option makes the cursor underlined instead of a box.

       +uc     This option makes the cursor a box instead of underlined.

       -ulc    This option disables the display of characters  with  underline
               attribute as color rather than with underlining.

       +ulc    This  option  enables  the display of characters with underline
               attribute as color rather than with underlining.

               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.

       -Sccn   This  option  allows  xterm  to  be used as an input and output
               channel for an existing program and is sometimes used  in  spe-
               cialized applications.  The option value specifies the last few
               letters of the name of a pseudo-terminal to use in slave  mode,
               plus  the  number  of  the  inherited  file descriptor.  If the
               option contains a "/" character, that delimits  the  characters
               used  for  the  pseudo-terminal  name from the file descriptor.
               Otherwise, exactly two characters are used from the option  for
               the pseudo-terminal name, the remainder is the file descriptor.
               Examples (the first two are  equivalent  since  the  descriptor
               follows the last "/"):

       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.

       -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.

       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".

       -bg color
               This  option  specifies  the color to use for the background of
               the window.  The corresponding  resource  name  is  background.
               The default is "XtDefaultBackground."

       -bw number
               This  option  specifies  the width in pixels of the border sur-
               rounding the window.

               This appears to be a legacy of older X releases.  It  sets  the
               borderWidth  resource  of  the  shell  widget,  and may provide
               advice to your window manager to set the thickness of the  win-
               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).
               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
       classes.  Application specific resources (e.g., "XTerm.NAME") follow:

       backarrowKeyIsErase (class BackarrowKeyIsErase)
               Tie  the  VTxxx  backarrowKey  and  ptyInitialErase   resources
               together  by  setting the DECBKM state according to whether the
               initial value of stty erase is a backspace (8) or delete  (127)
               character.   The  default  is "false", which disables this fea-
               ture.

       fullscreen (class Fullscreen)
               Specifies whether or not xterm should ask the window manager to
               use  a  fullscreen  layout  on startup.  Xterm accepts either a
               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.

               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.

       iconName (class IconName)
               Specifies the icon name.  The default is the application  name,
               e.g., "xterm".

       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)
                to an empty string.

       minBufSize (class MinBufSize)
               Specify  the minimum size of the input buffer, i.e., the amount
               of data that xterm requests  on  each  read.   The  default  is
               "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
               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.

       toolBar (class ToolBar)
               Specifies whether or not the toolbar should be displayed.   The
               default is "true."

       ttyModes (class TtyModes)
               Specifies a string containing terminal setting keywords and the
               characters to which they  may  be  bound.   Allowable  keywords
               include:  brk,  dsusp,  eof,  eol,  eol2, erase, erase2, flush,
               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."

   VT100 Widget Resources
       The following resources are specified  as  part  of  the  vt100  widget
       (class    VT100).    They   are   specified   by   patterns   such   as
       "XTerm.vt100.NAME".

       If your xterm is configured to support the "toolbar", then  those  pat-
       terns  need  an extra level for the form-widget which holds the toolbar
       and vt100 widget.  A wildcard between the  top-level  "XTerm"  and  the
       "vt100"  widget  makes  the  resource  settings  work for either, e.g.,
       "XTerm*vt100.NAME".

       activeIcon (class ActiveIcon)
               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-
               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."

       allowScrollLock (class AllowScrollLock)
               Specifies  whether  control sequences that set/query the Scroll
               Lock key should be allowed, as well as whether the Scroll  Lock
               key responds to user's keypress.  The default is "false."

               When this feature is enabled, xterm will sense the state of the
               Scroll Lock key each time  it  acquires  focus.   Pressing  the
               Scroll Lock key toggles xterm's internal state, as well as tog-
               gling the associated LED.  While the  Scroll  Lock  is  active,
               xterm attempts to keep a viewport on the same set of lines.  If
               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 "false."

               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:

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

               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
               if  they  are  not, this allows you to use the same prefix- and
               shifting operations with the Alt-key as with the Meta-key.  See
               altSendsEscape and metaSendsEscape.  The default is "false."

       altSendsEscape (class AltSendsEscape)
               This  is an additional keyboard operation that may be processed
               after the logic for metaSendsEscape.  It is only  available  if
               the altIsNotMeta resource is set.

               If  "true", Alt characters (a character combined with the modi-
               fier associated with left/right Alt-keys) 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 Alt is used in your key translations.
               If "false", Alt characters input  from  the  keyboard  cause  a
               shift to 8-bit characters (just like metaSendsEscape).  By com-
               bining the Alt- and Meta-modifiers, you can create  correspond-
               ing  combinations  of  ESC-prefix  and  8-bit  characters.  The
               default is "false."

       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
               true       false            same         overstrike
               true       false            different    use font
               true       true             ignored      overstrike

               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
               hollow  text cursor is displayed whenever the pointer moves out
               of the window or the window loses the input focus.  The default
               is "false."
               (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."

       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.  The default (backspace)  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
               completed; this feature is most useful with the visible bell.

       boldColors (class ColorMode)
               Specifies whether to combine bold attribute  with  colors  like
               the  IBM  PC,  i.e., map colors 0 through 7 to colors 8 through
               15.  These normally are the brighter versions of  the  first  8
               colors, hence bold.  The default is "true."

       boldFont (class BoldFont)
               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 provides 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 com-
               prise the fixed-pitch fonts that are used by xterm.  For  exam-
               ple
                       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.
               The default is "true."

       brokenSelections (class BrokenSelections)
               If true, xterm in 8-bit mode will interpret  STRING  selections
               as  carrying  text  in the current locale's encoding.  Normally
               STRING selections carry ISO-8859-1 encoded text.  Setting  this
               resource to "true" violates the ICCCM; it may, however, be use-
               ful for interacting with some broken X clients.  The default is
               "false."

       brokenStringTerm (class BrokenStringTerm)
               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.

       charClass (class CharClass)
               Specifies comma-separated lists of character class bindings  of
               the form [low-]high:value.  These are used in determining which
               sets of characters should be treated the same  when  doing  cut
               and paste.  See the CHARACTER CLASSES section.

       cjkWidth (class CjkWidth)
               Specifies  whether  xterm  should  follow  the traditional East
               Asian width convention.  When turned on, characters  with  East
               Asian  Ambiguous  (A) category in UTR 11 have a column width of
               2.  You may have to set this option to "true" if you have  some
               old  East  Asian terminal based programs that assume that line-
               drawing characters have a column width of 2.  If this  resource
               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)

       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.

               Resources  past color15 are available as a compile-time option.
               Due to a hardcoded limit in the X libraries on the total number
               of resources (to 400), the resources for 256-colors are omitted
               when wide-character support  and  luit  are  enabled.   Besides
               inconsistent  behavior  if  only  part  of  the  resources were
               allowed, determining the exact cutoff is difficult, and  the  X
               libraries  tend to crash if the number of resources exceeds the
               limit.  The color palette is  still  initialized  to  the  same
               default values, and can be modified via control sequences.

               On the other hand, the resource limit does permit including the
               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

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

       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."

       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)
               This specifies the color to use to display  underlined  charac-
               ters  if the "colorULMode" resource is enabled.  The default is
               "XtDefaultForeground."

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

       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."

               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."

       cursorUnderLine (class CursorUnderLine)
               Specifies whether to make the cursor underlined or a box.   The
               default is "false."

       cutToBeginningOfLine (class CutToBeginningOfLine)
               If  "false", triple clicking to select a line selects only from
               the current word  forward.   If  "true",  the  entire  line  is
               selected.  The default is "true."

       decTerminalID (class DecTerminalID)
               Specifies  the  emulation  level  (100=VT100, 220=VT220, etc.),
               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 "100".

       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.   The
               default is "false," for the latter.

       disallowedColorOps (class DisallowedColorOps)
               Specify  which  features  will  be disabled if allowColorOps is

               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.

       disallowedTcapOps (class DisallowedTcapOps)
               Specify which features will  be  disabled  if  allowTcapOps  is
               false.   This  is a comma-separated list of names.  The default
               value is
               SetTcap,GetTcap

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

               SetTcap
                    (not implemented)

               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.

               GetScreenSizeChars (19)
                    Report the size of the screen in characters 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)
                    Iconify window.

               PopTitle (23)
                    Pop title from internal stack.

               PushTitle (22)
                    Push title to internal stack.

               RaiseWin (5)
                    Raise the xterm window to the front of the stacking order.

               RefreshWin (7)
                    Refresh the xterm window.

               RestoreWin (1)
                    De-iconify window.

               SetSelection
                    Set selection data.

               SetWinLines
                    Resize to a given number of lines, at least 24.

               SetWinPosition (3)
                    Move window to given coordinates.

               SetWinSizeChars (8)
                    Resize the text area to given size in characters.

               SetWinSizePixels (4)
                    Resize the xterm window to given size in pixels.

               SetXprop
                    Set X property on top-level window.

               sented  as  a  single  character with the eighth bit turned on.
               The terminal is put into 8-bit mode.  If "false", Meta  charac-
               ters are converted into a two-character sequence with the char-
               acter itself preceded by ESC.  On startup, xterm tries  to  put
               the terminal into 7-bit mode.  The metaSendsEscape and altSend-
               sEscape resources may override this.  The default is "true."

               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
               that key as the Meta modifier.  It also looks for  the  NumLock
               key, to recognize the modifier which is associated with that.

               If  your  xmodmap configuration uses the same keycodes for Alt-
               and Meta-keys, xterm will only  see  the  Alt-key  definitions,
               since  those  are  tested  before Meta-keys.  NumLock is tested
               first.  It is important to keep these keys distinct;  otherwise
               some of xterm's functionality is not available.

       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.

       faceName (class FaceName)
               Specify the  pattern  for  scalable  fonts  selected  from  the
               FreeType  library if support for that library was compiled into
               xterm.  There is no default value.

               If not specified, or if there is no match for both  normal  and
               bold fonts, xterm uses the bitmap font and related resources.

               It  is  possible to select suitable bitmap fonts using a script
               such as this:

                   #!/bin/sh
                   FONT=`xfontsel -print`
                   test -n "$FONT" && xfd -fn "$FONT"

               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.

       faceSize3 (class FaceSize3)
               Specifies the pointsize of the third alternative font.

       faceSize4 (class FaceSize4)
               Specifies the pointsize of the fourth alternative font.

       faceSize5 (class FaceSize5)
               Specifies the pointsize of the fifth alternative font.

       faceSize6 (class FaceSize6)
               Specifies the pointsize of the sixth alternative font.

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

               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.

       font2 (class Font2)
               Specifies the name of the second alternative font.

       font3 (class Font3)
               Specifies the name of the third alternative font.

       font4 (class Font4)
               Specifies the name of the fourth alternative font.

       font5 (class Font5)
               Specifies the name of the fifth alternative font.

       font6 (class Font6)
               Specifies the name of the sixth alternative font.

       fontDoublesize (class FontDoublesize)
               Specifies  whether  xterm should attempt to use font scaling to
               draw double-sized characters.  Some older font  servers  cannot
               do  this  properly,  will  return misleading font metrics.  The
               default is "true".  If disabled, xterm  will  simulate  double-
               sized  characters  by  drawing  normal  characters  with spaces
               between them.

       fontWarnings (class FontWarnings)
               Specify whether xterm should report an error  if  it  fails  to
               load a font:

               0    Never report an error (though the X libraries may).

               1    Report  an  error if the font name was given as a resource
                    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:

               -    The  fixed-pitch  ISO-8859-*-encoded  fonts  used by xterm
                    normally have the VT100 line-drawing glyphs in cells 1-31.
                    Other  fixed-pitch  fonts may be more attractive, but lack

               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.
               There is no default for this resource.

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

       highlightColorMode (class HighlightColorMode)
               Specifies whether xterm should use highlightTextColor and high-
               lightColor to override the reversed foreground/background  col-
               ors  in  a  selection.  The default is unspecified: at startup,
               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:

               HCM
                  highlightColorMode

               HR highlightReverse

               HBG
               false     true    default   default   bg/fg
               false     true    default   set       bg/fg
               false     true    set       default   fg/HBG
               false     true    set       set       fg/HBG
               ------------------------------------------------------
               true      false   default   default   bg/fg

               true      false   set       default   bg/HBG
               true      false   set       set       HFG/HBG
               ------------------------------------------------------
               true      true    default   default   fg/fg (useless)
               true      true    default   set       HFG/fg
               true      true    set       default   fg/HBG
               true      true    set       set       HFG/HBG

               ------------------------------------------------------
               default   true    default   default   bg/fg
               default   true    default   set       bg/fg
               default   true    set       default   fg/HBG
               default   true    set       set       HFG/HBG
               ------------------------------------------------------

       highlightReverse (class HighlightReverse)
               Specifies whether xterm should reverse the selection foreground
               and background colors when selecting  text  with  reverse-video
               attribute.   This  applies only to the highlightColor and high-
               lightTextColor resources, e.g., to match the  color  scheme  of
               xwsh.   If "true", xterm reverses the colors, If "false", xterm
               does not reverse colors, The default is "true."

       highlightSelection (class HighlightSelection)
               If "false", selecting with the mouse highlights  all  positions
               on  the  screen  between the beginning of the selection and the
               current position.  If "true", xterm highlights only  the  posi-
               tions  that  contain text that can be selected.  The default is
               "false."

               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."

       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)
               Specifies  whether  characters  with  the  underline  attribute
               should  be displayed in an italic font or as underlined charac-
               ters.  It is implemented only for TrueType fonts.

       jumpScroll (class JumpScroll)
               Specifies whether or not jump scroll should be used.  This cor-
               responds  to  the  VT102  DECSCLM private mode.  The default is
               "true."  See fastScroll for a variation.

       keepSelection (class KeepSelection)
               Specifies whether xterm will keep the selection even after  the
               selected  area was touched by some output to the terminal.  The
               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)
                   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-
               fonts(utf8Fonts, Utf8Fonts) action to  load  font  name  subre-
               sources  of  the VT100 widget.  That is, resource patterns such
               as  "*vt100.utf8Fonts.font"  will  be  loaded,  and  (if   this
               resource  is enabled), override the normal fonts.  If no subre-
               sources are found, the  normal  fonts  such  as  "*vt100.font",
               etc.,  are used.  The resource files distributed with xterm use
               ISO-10646-1 fonts, but do not rely on them unless you are using
               the locale mechanism.

       localeFilter (class LocaleFilter)
               Specifies  the  file  name  for  the encoding converter from/to
               locale encodings and UTF-8 which is used with the -lc option or
               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
               should  put  those  within  a  shell script to execute the con-
               verter, and set this resource to point to the shell script.

       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
               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
               wide character width calculation:

               cjkWidth   mkWidth   Action
               ---------------------------------------------------------------
               false      false     use system tables subject to mkSamplePass
               false      true      use built-in tables
               true       false     use built-in CJK tables
               true       true      use built-in CJK tables

       modifyCursorKeys (class ModifyCursorKeys)
               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 cursor-key.  The default is "2":

               Set it to -1 to disable it.
               Set it to 0 to use the old/obsolete behavior.
               Set it to 1 to prefix modified sequences with CSI.
               Set it to 2 to force the modifier to be the second parameter if
               it would otherwise be the first.
               Set it to 3 to mark 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:

               Set it to -1 to permit the user to use shift- and control-modi-
               fiers to construct function-key strings using the normal encod-
               ing scheme.
               Set it to 0 to use the old/obsolete behavior.
               Set it to 1 to prefix modified sequences with CSI.
               Set it to 2 to force the modifier to be the second parameter if
                    adds twice the value given by the ctrlFKeys resource.

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

               As a special case, legacy (when  oldFunctionKeys  is  true)  or
               vt220  (when  sunKeyboard is true) keyboards interpret only the
               Control-modifier  when  constructing  numbered   function-keys.
               This  is done to provide compatible keyboards for DEC VT220 and
               related terminals that implement user-defined keys (UDK).

       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."
               start  action) are interpreted according to the resource values
               of on2Clicks, etc.  The resource value can be one of these:

               word
                  Select a "word" as determined  by  the  charClass  resource.
                  See the CHARACTER CLASSES section.

               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.

               Specifies whether the window would be raised when Control-G  is
               received.  The default is "false."

               If  the  window is iconified, this has no effect.  However, the
               zIconBeep resource provides you with the ability to  see  which
               iconified windows have sounded a bell.

       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
               Specify  the  range of text which is printed to a file when the
               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)
       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
               server is not responding.   This  is  a  different  issue  than
               unsupported  preedit  type,  etc.  You may encounter retries if
               your X configuration (and its libraries)  are  missing  pieces.
               Setting  this  resource to zero ``0'' will cancel the retrying.
               The default is ``3''.

               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".

       scrollBar (class ScrollBar)
               Specifies whether or not the  scrollbar  should  be  displayed.
               The default is "false."

       scrollBarBorder (class ScrollBarBorder)
               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."

       tekGeometry (class Geometry)
               Specifies the preferred size and position of the Tektronix win-
               dow.  There is no default for this resource.

       tekInhibit (class TekInhibit)
               Specifies whether or not the escape sequence to enter Tektronix
               mode should be ignored.  The default is "false."

       tekSmall (class TekSmall)
               Specifies whether or not the Tektronix mode window should start
               in its smallest size if no explicit geometry is given.  This is
               useful when running xterm on displays with small screens.   The
               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 utf8Titles
                    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
               trim  trailing spaces from text which is selected.  It does not
               affect spaces which result in a wrapped line, nor will it  trim
               the  trailing  newline  from  your  selection.   The default is
               "false."

       underLine (class UnderLine)
               This specifies whether or not text with the underline attribute
               should be underlined.  It may be desirable to disable underlin-
               ing when color is being used for the underline attribute.   The
               default is "true."

               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.

               true (1)
                      Use the UTF-8 fonts.  The menu entry is enabled,  allow-
                      ing the choice of fonts to be changed at runtime.

               always (2)
                      Always use the UTF-8 fonts.  This also disables the menu
                      entry.

               default (3)
                      At startup, the  resource  is  set  to  true  or  false,

       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."

       visualBellDelay (class VisualBellDelay)
               Number  of milliseconds to delay when displaying a visual bell.
               Default is 100.  If set to zero, no visual bell  is  displayed.
               This  is useful for very slow displays, e.g., an LCD display on
               a laptop.

       vt100Graphics (class VT100Graphics)
               This specifies whether xterm will interpret VT100 graphic char-
               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
               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.

   Tek4014 Widget Resources
       The  following  resources  are  specified as part of the tek4014 widget
       (class  Tek4014).   These   are   specified   by   patterns   such   as
       "XTerm.tek4014.NAME":

               Specifies the small font to use in the Tektronix window.

       ginTerminator (class GinTerminator)
               Specifies  what character(s) should follow a GIN report or sta-
               tus report.  The possibilities are "none," which sends no  ter-
               minating  characters,  "CRonly,"  which sends CR, and "CR&EOT,"
               which sends both CR and EOT.  The default is "none."

       height (class Height)
               Specifies the height of the Tektronix window in pixels.

       initialFont (class InitialFont)
               Specifies which of the four Tektronix fonts to  use  initially.
               Values  are  the  same  as  for  the  set-tek-text action.  The
               default is "large."

       width (class Width)
               Specifies the width of the Tektronix window in pixels.

   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.

       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):

              -  Double-clicking selects by words.

              -  Triple-clicking selects by lines.

              -  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.

       Pointer button three (usually right)  extends  the  current  selection.
       (Without loss of generality, you can swap "right" and "left" everywhere
       in the rest of this paragraph.)  If pressed while closer to  the  right
       edge  of  the  selection  than the left, it extends/contracts the right
       edge of the selection.  If you contract the  selection  past  the  left
       edge  of  the  selection, xterm assumes you really meant the left edge,
       restores the original selection, then extends/contracts the  left  edge
       of the selection.  Extension starts in the selection unit mode that the
       last selection or extension was performed in; you can multiple-click to
       cycle through them.

       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.

       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).

   CLIPBOARD
       When  configured to use the clipboard (see resource selectToClipboard),
       the problem with persistence  of  ownership  is  bypassed.   Otherwise,
       there  is  no  difference  regarding  the  data which can be passed via
       selection.

   SELECTION TARGETS
       The different types of data which are passed depend on what the receiv-
       ing client asks for.  These are termed selection targets.

       When  asking for the selection data, xterm tries the following types in
       this order:

              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-
       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
       The xterm mainMenu pops up when the "control" key  and  pointer  button
       one  are  pressed  in a window.  This menu contains items that apply to
       both the VT102 and Tektronix windows.  There are several sections:

       Commands for managing X events:

              Toolbar
                     Clicking on the "Toolbar" menu entry hides the toolbar if
                     it is visible, and shows it if it is not.

              Secure Keyboard (securekbd)
                     The  Secure Keyboard mode is helpful when typing in pass-
                     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.
                     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.

              Backarrow Key (BS/DEL) (backarrow key)
                     Modifies  the  behavior  of  the backarrow key, making it
                     transmit either a backspace (8) or delete  (127)  charac-
                     ter.  This corresponds to the backarrowKey resource.

              Alt/NumLock Modifiers (num-lock)
                     Controls the treatment of Alt- and NumLock-key modifiers.
                     This corresponds to the numLock resource.

              Meta Sends Escape (meta-esc)
                     Controls whether Meta keys are converted into a two-char-
                     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

              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 Scrollbar (scrollbar)
                     Enable (or disable) the scrollbar.  This  corresponds  to
                     the -sb option and the scrollBar resource.

              Enable Jump Scroll (jumpscroll)
                     Enable  (or disable) jump scrolling.  This corresponds to
                     the -j option and the jumpScroll resource.

              Enable Reverse Video (reversevideo)
                     Enable (or disable) reverse-video.  This  corresponds  to
                     the -rv option and the reverseVideo resource.

              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.
                     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)
                     Tell  xterm  whether  to use the PRIMARY or CLIPBOARD for
                     SELECT tokens in the  translations  resource  which  maps
                     keyboard and mouse actions to select/paste actions.  This
                     corresponds to the selectToClipboard resource.  There  is
                     no corresponding command-line option.

              Enable Visual Bell (visualbell)
                     Enable (or disable) visible bell (i.e., flashing) instead
                     of an audible bell.  This corresponds to the  -vb  option
                     and the visualBell resource.

              Enable Bell Urgency (bellIsUrgent)
                     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.

                     Reset scroll regions.  This can be convenient  when  some
                     program  has  left  the  scroll  regions  set incorrectly
                     (often a problem when using VMS or TOPS-20).  This corre-
                     sponds to the VT220 DECSTR control sequence.

              Do Full Reset (hardreset)
                     The full reset entry will clear the screen, reset tabs to
                     every eight columns, and reset the terminal  modes  (such
                     as  wrap  and smooth scroll) to their initial states just
                     after xterm has  finished  processing  the  command  line
                     options.   This  corresponds  to  the  VT102  RIS control
                     sequence, with a few obvious differences.   For  example,
                     your  session  is  not disconnected as a real VT102 would
                     do.

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

              Large (font5)
                     Set the font to that given by the *VT100.font5 resource.

              Huge (font6)
                     Set the font to that given by the *VT100.font6 resource.

              Escape Sequence
                     This allows you to set the font last specified by the Set
                     Font  escape  sequence  (see  the  document Xterm Control
                     Sequences).

              Selection (fontsel)
                     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.
                     Initially the checkmark is set according to both the utf8
                     and  utf8Fonts  resource values.  If the latter is set to
                     "always", the checkmark is disabled.  Likewise, if  there
                     are  no  fonts  given in the utf8Fonts subresources, then
                     the checkmark also is disabled.

                     The standard XTerm app-defaults file defines both sets of
                     fonts,  while  the  UXTerm app-defaults file defines only
                     one set.  assuming the standard app-defaults files,  this
                     command  will  launch  xterm able to switch between UTF-8
                     and ISO-8859-1 encoded fonts:

                         uxterm -class XTerm


       The fourth section allows you to enable or disable  special  operations
       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)

       Windows:

              Show VT Window (vtshow)

              Switch to VT Mode (vtmode)

              Hide Tek Window (tekhide)

SECURITY
       X environments differ in their security consciousness.   Most  servers,
       run  under  xdm,  are  capable  of using a "magic cookie" authorization
       scheme that can provide a reasonable level of security for many people.
       If  your  server is only using a host-based 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  ser-
       vices  of  the X protocol to snoop on your activities, potentially cap-
       turing a transcript of  everything  you  type  at  the  keyboard.   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  allowSendE-
       vents  provides  some  protection  against rogue applications tampering
       with your programs, guarding against a snooper is harder.

       The possibility of an application spying on your keystrokes is of  par-
       ticular  concern when you want to type in a password or other sensitive
       data.  The best solution to this problem is to use a better  authoriza-
       tion  mechanism  than  is provided by X.  Given all of these caveats, a
       simple mechanism exists for protecting 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.  This ensures that
       you know which window is accepting your keystrokes.  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.

       have different preferences for what should be  selected  (for  example,
       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] = {
           /* NUL  SOH  STX  ETX  EOT  ENQ  ACK  BEL */

       characters should be treated the same way as  characters  and  numbers.
       This is useful for cutting and pasting electronic mailing addresses and
       filenames.

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

       allow-color-ops(on/off/toggle)
               This  action  set  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 set 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 set or toggles the allowSendEvents resource and is
               also invoked by the allowsends entry in mainMenu.

       allow-tcap-ops(on/off/toggle)
               This action set 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  set  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 set or toggles the allowWindowOps resource  and  is
               also invoked by the allow-window-ops entry in fontMenu.

       alt-sends-escape()
               This action toggles the state of the eightBitInput resource.
               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()
               Asks the window manager to change the window to full-screen.

       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.

       ignore()
               This  action  ignores  the event but checks for special pointer

               The  term  "eight-bit" is misleading: xterm checks if the key's
               value is less than 128.  If so, xterm adds 128  to  the  value,
               setting  its  eighth  bit.   Otherwise  xterm sends an ESC byte
               before the key.  In other applications' documentation, that  is
               referred to as a "meta key".

       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()
               Resizes the window to fill the screen.

       meta-sends-escape()
               This action toggles the state of the metaSendsEscape resource.

       popup-menu(menuname)
               noFormFeed
                    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.
               redraw entry in mainMenu.

       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.

       scroll-forw(count [,units [,mouse] ])

               This action puts the currently selected text into  all  of  the
               selections  or cutbuffers specified by destname.  It also sends
               a mouse position and updates the internal  selection  state  to
               reflect the end of the selection process.

       select-extend()
               This  action  tracks the pointer and extends the selection.  It
               should only be bound to Motion events.

               This action controls whether or not the vt or tek  windows  are
               visible.   It  is  also  invoked  from  the  tekshow and vthide
               entries in vtMenu and the vtshow and tekhide  entries  in  tek-
               Menu.

       set-visual-bell(on/off/toggle)
               This action toggles the visualBell resource and is also invoked
               by the visualbell entry in vtMenu.

       set-vt-font(d/1/2/3/4/5/6/e/s [,normalfont [, boldfont]])
               This action sets the font or fonts currently being used in  the
               VT102  window.   The  first argument is a single character that
               specifies the font to be used:

               d or D indicate the default font (the font initially used  when
                      xterm was started),

               1  through  6 indicate the fonts specified by the font1 through
                      font6 resources,

               e or E indicate the normal and bold fonts that  have  been  set
                      through  escape  codes  (or  specified as the second and
                      third action arguments, respectively), and

       soft-reset()
               This action resets the scrolling region  and  is  also  invoked
               from the softreset entry in vtMenu.  The effect is identical to
               a soft reset (DECSTR) control sequence.

       spawn-new-terminal(params)
               Spawn a new xterm process.  This is available on systems  which
               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.

               If parameters are given in the action, pass  them  to  the  new
               xterm process.

       start-extend()
               This  action  is similar to select-start except that the selec-
               tion is extended to the current pointer location.

       start-cursor-extend()
               This action is similar to select-extend except that the  selec-
               tion is extended to the current text cursor position.

       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 and is also invoked  by
               the tekpage entry in tekMenu.

       tek-reset()
               This  action resets the Tektronix window and 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:
               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.

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

       The default bindings in the Tektronix window are:

                            ~Meta<KeyPress>: insert-seven-bit() \n\
                             Meta<KeyPress>: insert-eight-bit() \n\

       Here is an example which uses shifted select/paste to copy to the clip-
       board,  and  unshifted select/paste for the primary selection.  In each
       case, a (different) cut buffer is  also  a  target  or  source  of  the
       select/paste  operation.  It is important to remember however, that cut
       buffers store data in ISO-8859-1 encoding, while selections  can  store
       data  in  a  variety  of  formats  and encodings.  While xterm owns the
       selection, it highlights it.  When it loses the selection,  it  removes
       the  corresponding  highlight.  But you can still paste from the corre-
       sponding cut buffer.

           *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 how of 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.,

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

       XTERM_SHELL
            is  set  to the pathname of the program which is invoked.  Usually
            that is a shell program, e.g., /bin/sh.  Since it is not necessar-
            ily a shell program however, it is distinct from "SHELL".

       XTERM_VERSION
            is  set  to  the string displayed by the -version option.  That is
            normally an identifier for the X Window libraries  used  to  build
            xterm, followed by xterm's patch number in parenthesis.  The patch
            number is  also  part  of  the  response  to  a  Secondary  Device
            Attributes (DA) control sequence (see Xterm Control Sequences).

       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.

       /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.

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
       below, with a brief explanation.

       1    is  used  for  miscellaneous errors, usually accompanied by a spe-
            cific message,

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.

       Many of the options are not resettable after xterm starts.

       This program still needs to be rewritten.  It should be split into very
       modular  sections, with the various emulators being completely separate
       widgets that do not know about each other.  Ideally, you'd like  to  be
       able  to  pick and choose emulator widgets and stick them into a single
       control widget.

       There needs to be a dialog box to allow entry  of  the  Tek  COPY  file
       name.
