NAME

       xterm - terminal emulator for X

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
       terminals  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),
       Tektronix 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
       terminal 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 window.

EMULATIONS

       The   VT102   emulation  is  fairly  complete,  but  does  not  support
       autorepeat.  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
       control  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
       directory  xterm  is  started  in,  or  the  home directory for a login
       xterm).

       Not all of the  features  described  in  this  manual  are  necessarily
       available  in  this  version  of  xterm.   Some  (e.g.,  the  non-VT220
       extensions) are available only if they were  compiled  in,  though  the
       most commonly-used are in the default configuration.

OTHER FEATURES

       Xterm  automatically highlights the text cursor when the pointer enters
       the window (selected) and unhighlights it when the pointer  leaves  the
       window  (unselected).  If the window is the focus window, then the text
       cursor is highlighted no matter where the pointer is.

       In VT102 mode, there are escape sequences to activate and deactivate an
       alternate  screen buffer, which is the same size as the display area of
       the window.  When activated, the current screen is saved  and  replaced
       with the alternate screen.  Saving of lines scrolled off the top of the
       window is disabled until the normal screen is restored.  The termcap(5)
       entry  for  xterm  allows  the  visual  editor  vi(1)  to switch to the
       alternate 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
       (currently 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
       configuration  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
               generates  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
       option  cannot be used with this parameter since it uses all parameters
       following the option.

       The other options are used to control the appearance and behavior.  Not
       all options are necessarily configured into your copy of xterm:

       -132    Normally,  the  VT102  DECCOLM  escape  sequence  that switches
               between 80 and 132 column mode is ignored.  This option  causes
               the  DECCOLM  escape  sequence  to be recognized, and the xterm
               window will resize appropriately.

       -ah     This option indicates that xterm should  always  highlight  the
               text  cursor.   By  default,  xterm  will display a hollow text
               cursor whenever the focus is lost or  the  pointer  leaves  the
               window.

       +ah     This   option  indicates  that  xterm  should  do  text  cursor
               highlighting 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
               distance  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
               display  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".

       -cc characterclassrange:value[,...]
               This sets classes indicated by the given ranges  for  using  in
               selecting  by  words.   See  the  section  specifying character
               classes.  and discussion of the charClass resource.

       -cjk_width
               Set  the  cjkWidth  resource  to  "true".   When   turned   on,
               characters  with  East  Asian  Ambiguous (A) category in UTR 11
               have a column width of 2.  Otherwise, they have a column  width
               of  1.   This  may be useful for some legacy CJK text terminal-
               based programs assuming box  drawings  and  others  to  have  a
               column  width  of  2.   It  also  should  be turned on when you
               specify a TrueType CJK double-width  (bi-width/monospace)  font
               either  with -fa at the command line or faceName resource.  The
               default is "false"

       +cjk_width
               Reset the cjkWidth resource.

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

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

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

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

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

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

       -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
               colors: the vt100 foreground and background  colors,  its  text
               cursor  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
               colors.  The option sets the dynamicColors option to "true".

       -e program [ arguments ... ]
               This  option  specifies  the  program  (and  its  command  line
               arguments) 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 must be the last option on the command line.

       -en encoding
               This  option  determines  the encoding on which xterm runs.  It
               sets the locale  resource.   Encodings  other  than  UTF-8  are
               supported by using luit.  The -lc option should be used instead
               of -en for systems with locale support.

       -fb font
               This option specifies a font to be used  when  displaying  bold
               text.  It sets the boldFont resource.

               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
               compiled    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
               to let it use the full-screen for display, e.g., without window
               decorations.  It sets the fullscreen resource to "true".

       +fullscreen
               This  option  indicates  that  xterm  should not ask the window
               manager to let it use the full-screen for display.  It sets the
               fullscreen resource to "false".

       -fw font
               This  option  specifies the font to be used for displaying wide
               text.  By default, it will attempt to use a font twice as  wide
               as  the  font  that  will  be  used to draw normal text.  If no
               double-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
               selection.  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
               selection.  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
               window,  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-
               terminal'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
               reference, if available.

       -im     Turn on the useInsertMode resource, which forces use of  insert
               mode  by  adding appropriate entries to the TERMCAP environment
               variable.

       +im     Turn off the useInsertMode resource.

       -into windowId
               Given an X window identifier (a decimal  integer),  xterm  will
               reparent  its  top-level  shell widget to that window.  This is
               used to embed xterm within other applications.

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

       +lc     Turn off support of automatic selection  of  locale  encodings.
               Conventional 8bit mode or, in UTF-8 locales or with -u8 option,
               UTF-8 mode will be used.

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

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

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

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

               The -ls flag and the loginShell resource are ignored if  -e  is
               also  given,  because xterm does not know how to make the shell
               start the given command after whatever it does  when  it  is  a
               login  shell  - the user's shell of choice need not be a Bourne
               shell after all.  Also,  xterm -e  is  supposed  to  provide  a
               consistent  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
               terminal.

       -mk_width
               Set the mkWidth resource to "true".  This  makes  xterm  use  a
               built-in  version of the wide-character width calculation.  The
               default is "false"

       +mk_width
               Reset the mkWidth resource.

       -ms color
               This option specifies the color to  be  used  for  the  pointer
               cursor.  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
               boldColors 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
               requiring an extra round trip to the server  to  find  out  the
               previous value.  In practice this should never be a problem.

       +samename
               Always send title and icon name change requests.

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

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

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

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

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

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

       -si     This  option  indicates  that  output  to  a  window should not
               automatically 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,
               indicates that xterm should set up session manager callbacks.

       +sm     This option indicates that xterm  should  not  set  up  session
               manager 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
               windows is done using the "Options" menus.  Termcap(5)  entries
               that   work   with   xterm   "tek4014,"  "tek4015,"  "tek4012,"
               "tek4013," "tek4010," and "dumb."  xterm automatically searches
               the  termcap file in this order for these entries and then sets
               the "TERM" and the "TERMCAP" environment variables.

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

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

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

       -ti term_id
               Specify  the  name used by xterm to select the correct response
               to terminal ID queries.  It also specifies the emulation level,
               used  to  determine  the  type  of  response  to  a  DA control
               sequence.  Valid values include vt52, vt100, vt101, vt102,  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
               functions, 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
               terminal  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.

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

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

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

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

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

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

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

       +wc     This option resets the wideChars resource.

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

       +wf     This  option  indicates  that  xterm  should  not  wait  before
               starting 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
               immediately, 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
               console  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
               specialized 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 "/"):

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

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

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

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

        #geom  This option  specifies  the  preferred  position  of  the  icon
               window.   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
               equivalent to -rv.

       -w number
               This option  specifies  the  width  in  pixels  of  the  border
               surrounding  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
               surrounding 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
               window   frame.    Most   window   managers  do  not  use  this
               information.  See the  -b  option,  which  controls  the  inner
               border of the xterm window.

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

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

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

       -font font
               This is the same as -fn.

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

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

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

       -rv     This option indicates that reverse video should be simulated by
               swapping   the   foreground   and   background   colors.    The
               corresponding 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
               separate 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
               feature.

       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.

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

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

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

               The default is "false."

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

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

               See also the keyboardType resource.

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

       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,
               tcapFunctionKeys  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
               support; 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
               minBufSize  resource.   It  will be increased as needed to make
               that value evenly divide this one.

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

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

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

       menuLocale (class MenuLocale)
                Specify  the  locale  used for character-set computations when
                loading the popup menus.  Use this to  improve  initialization
                performance   of  the  Athena  popup  menus,  which  may  load
                unnecessary (and very large) fonts, e.g., in a  locale  having
                UTF-8 encoding.  The default is "C" (POSIX).

                To  use  the current locale (only useful if you have localized
                the resource settings for the menu entries), set the  resource
                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
               translations 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 settings.

       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
               initialization  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 interaction.

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

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

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

               See also the keyboardType resource.

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

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

               See also the keyboardType resource.

       sunKeyboard (class SunKeyboard)
               Specifies  whether  or  not  Sun/PC  keyboard  layout should be
               assumed rather than DEC VT220.  This causes the keypad  "+'  to
               be mapped to ",'.  and CTRL F1-F12 to F11-F20, depending on the
               setting of the ctrlFKeys resource.  so  xterm  emulates  a  DEC
               VT220   more   accurately.    Otherwise   (the   default,  with
               sunKeyboard 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
               environment 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,
               intr, kill, lnext, quit,  rprnt,  start,  status,  stop,  susp,
               swtch  and weras.  Control characters may be specified as ^char
               (e.g., ^c or ^u) and ^? may be used to indicate  delete  (127).
               Use  ^-  to  denote  undef.   Use \034 to represent ^\, since a
               literal backslash in an X resource escapes the next character.

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

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

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

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

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

       waitForMap (class WaitForMap)
               Specifies  whether  or  not  xterm  should wait for the initial
               window 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
               iconified 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
       patterns  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
               application  icon windows.  Some window managers will allow you
               to enter keystrokes into the active icon window.   The  default
               is "false."

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

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

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

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

       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
               toggling 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
               configurations,  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
               (generated using the X protocol SendEvent  request)  should  be
               interpreted  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
               forcefully 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
                  supports.  This is  a  constant,  depending  on  how  it  is
                  compiled,  typically  16.   It  does not change if you alter
                  resource settings, e.g., the boldColors resource.

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

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

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

       altIsNotMeta (class AltIsNotMeta)
               If  "true", treat the Alt-key as if it were the Meta-key.  Your
               keyboard may happen to be configured so they are the same.  But
               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
               modifier 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 combining the  Alt-  and  Meta-modifiers,
               you  can  create  corresponding  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
               handle 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
               highlighted 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."

       alwaysUseMods (class AlwaysUseMods)
               Override the numLock resource, telling xterm to use the Alt and
               Meta  modifiers  to  construct  parameters  for  function   key
               sequences  even  if  those modifiers appear in the translations
               resource.  Normally xterm checks if Alt or Meta is  used  in  a
               translation  that  would  conflict with function key modifiers,
               and will ignore these modifiers  in  that  special  case.   The
               default is "false."

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

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

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

       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
               timeout  to  await  input  (i.e.,  to  support  the Xaw3d arrow
               scrollbar).  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
               control 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
               manager 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)
               Specifies  the  name  of  the  bold  font  to  use  instead  of
               overstriking.  There is no default for this resource.

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

               See   also   the  discussion  of  boldMode  and  alwaysBoldMode
               resources.

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

               Note that xterm has one bold font which you may set explicitly.
               Xterm  attempts  to  derive  a  bold  font  for  the other font
               selections (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
               provide 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
               comprise  the  fixed-pitch  fonts  that are used by xterm.  For
               example
                       FontPath         "/usr/lib/X11/fonts/misc/"

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

               Depending on your configuration, the font server may  have  its
               own  configuration  file.  The same ":unscaled" can be added to
               its  configuration  file  at   the   end   of   the   directory
               specification 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
               useful for interacting with some broken X clients.  The default
               is "false."

       brokenStringTerm (class BrokenStringTerm)
               provides a work-around for some ISDN  routers  which  start  an
               application  control string without completing it.  Set this to
               "true" if xterm appears to freeze when connecting.  The default
               is "false."

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

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

               Each should end with a string-terminator (a  special  character
               which  cannot  appear  in  these  strings).   Ordinary  control
               characters found within the string are not  ignored;  they  are
               processed  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)

       color1 (class Color1)

       color2 (class Color2)

       color3 (class Color3)

       color4 (class Color4)

       color5 (class Color5)

       color6 (class Color6)

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

       color8 (class Color8)

       color9 (class Color9)

       color10 (class Color10)

       color11 (class Color11)

       color12 (class Color12)

       color13 (class Color13)

       color14 (class Color14)

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

       color16 (class Color16)

       through

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

               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
               default is "false."

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

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

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

       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
               disables all colors, including this.  The default is "false."

       colorUL (class ColorUL)
               This   specifies   the  color  to  use  to  display  underlined
               characters 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."

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

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

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

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

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

       cutNewline (class CutNewline)
               If  "false",  triple clicking to select a line does not include
               the Newline at the end of the line.  If "true", the Newline  is
               selected.  The default is "true."

       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
               represented  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
               layout 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
               false.  This is a comma-separated list of names.   The  default
               value is
               SetColor,GetColor,GetAnsiColor

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

               SetColor
                    Set a specific dynamic color.

               GetColor

               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,SetSelection,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.

               GetSelection
                    Report selection data as a base64 string.

               GetWinPosition (13)
                    Report xterm window position as numbers.

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

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

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

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

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

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

               FullscreenWin (10)
                    Use  full  screen  (i.e.,  resize  to screen size, without

               SetXprop
                    Set X property on top-level window.

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

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

       eightBitInput (class EightBitInput)
               If  "true",  Meta  characters (a single-byte character combined
               with the  Meta  modifier  key)  input  from  the  keyboard  are
               presented  as a single character with the eighth bit turned on.
               The  terminal  is  put  into  8-bit  mode.   If  "false",  Meta
               characters are converted into a two-character sequence with the
               character itself preceded by ESC.  On startup, xterm  tries  to
               put  the  terminal  into  7-bit  mode.  The metaSendsEscape and
               altSendsEscape 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
               modifiers  for  shift,  (caps)  lock  and control, as well as 5
               additional modifiers which are generally used to configure  key
               modifiers.   xterm  inspects  the  same information to find the
               modifier 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"

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

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

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

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

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

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

               Although the default is "14.0", this may not be the same as the
               pointsize for the default bitmap font, i.e., that assigned with
               the -fn option, or the font resource.  For example, the "fixed"
               font  usually has a pointsize of "8.0".  If you set faceSize to
               match the size of  the  bitmap  font,  then  switching  between
               bitmap   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."

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

               NOTE: some resource files use patterns such as
               *font: fixed

               which are overly broad, affecting both
               xterm.vt100.font

               and
               xterm.vt100.utf8Fonts.font

               which is probably not what you intended.

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

       font1 (class Font1)
               Specifies the name of the first alternative font.

       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
                    these glyphs.

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

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

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

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

       formatOtherKeys (class FormatOtherKeys)
               Overrides  the  format  of  the  escape sequence used to report
               modified 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
               compares 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
               highlightColor to override the  reversed  foreground/background
               colors 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

               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
               highlightTextColor 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
               positions  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."

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

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

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

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

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

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

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

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

       italicULMode (class ColorAttrMode)
               Specifies  whether  characters  with  the  underline  attribute
               should  be  displayed  in  an  italic  font  or  as  underlined
               characters.  It is implemented only for TrueType fonts.

       jumpScroll (class JumpScroll)
               Specifies whether or not jump  scroll  should  be  used.   This
               corresponds  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)
               Limits resizing of the screen via control sequence to  a  given
               multiple of the display dimensions.  The default is "1".

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

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

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

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

               false
                   xterm  will  use  conventional  8bit  mode  or  UTF-8  mode
                   according 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
               subresources  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
               subresources 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
               converter, 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
               types near the right margin.  The default is "false."

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

       mkSamplePass (class MkSamplePass)
               If mkSampleSize is nonzero,  and  mkWidth  (and  cjkWidth)  are
               false,  on  startup  xterm  compares its built-in tables to the
               system's wide character width data to decide if it will use the
               system's  data.   It  tests  the  first  mkSampleSize character
               values, 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
               initializing  wide  character  width calculations.  The default
               (number 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
               modifyCursorKeys:

               Set  it  to  -1  to  permit the user to use shift- and control-
               modifiers to construct function-key strings  using  the  normal
               encoding 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
               it would otherwise be the first.
               Set it to 3 to mark the sequence with a ">" to hint that it  is
               private.

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

               Control
                    adds the value given by the ctrlFKeys resource.

               Shift
                    adds twice the value given by the ctrlFKeys resource.

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

               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
               Control-, 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
                    control 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
               asynchronously.  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
               function keys F1 to F4, for  compatibility  with  X  Consortium
               xterm.   Otherwise,  it  uses  the VT100-style codes for PF1 to
               PF4.  The default is "false."

       on2Clicks (class On2Clicks)

       on3Clicks (class On3Clicks)

       on4Clicks (class On4Clicks)

       on5Clicks (class On5Clicks)
               Specify  selection  behavior  in  response  to  multiple  mouse
               clicks.    A  single  mouse  click  is  always  interpreted  as
               described  in  the  SELECTION  section  (see  POINTER   USAGE).
               Multiple  mouse  clicks  (using  the button which activates the
               select-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
               determines the  maximum  number  of  clicks  by  the  onXClicks
               resource values which are set.

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

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

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

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

               0  never

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

               2  always.

       pointerShape (class Cursor)
               Specifies the name of the shape of the pointer.  The default is
               "xterm."

       popOnBell (class PopOnBell)
               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
               printModeImmediate  resource to tell it to use escape sequences
               to reconstruct the video attributes and colors.  This uses  the
               same  values  as  the printAttributes resource.  The default is
               "0".

       printModeOnXError (PrintModeOnXError)
               Xterm  implements  the  printFileOnXError  feature  using   the
               printer  feature,  although the output is written directly to a
               file.  You can use the printModeOnXError resource to tell it to
               use  escape  sequences  to reconstruct the video attributes and
               colors.  This uses  the  same  values  as  the  printAttributes
               resource.  The default is "0".

       printOptsImmediate (PrintOptsImmediate)
               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
                      normal 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
               interpreted 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
               command.  The default is "false."

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

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

       printerExtent (class PrinterExtent)
               Controls whether a print page function will  print  the  entire
               page  (true),  or  only  the  the  portion within the scrolling
               margins (false).  The default is "false."

       printerFormFeed (class PrinterFormFeed)
               Controls whether a form feed is sent to the printer at the  end
               of a print page function.  The default is "false."

       printerNewLine (class PrinterNewLine)
               Controls whether a newline is sent to the printer at the end of
               a print page function.  The default is "true."

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

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

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

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

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

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

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

                    If  there  is  no  faceName  resource  set,  then  runtime
                    switching  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''.

       reverseVideo (class ReverseVideo)
               Specifies  whether  or  not  reverse video should be simulated.
               The default is "false."

               There are several aspects to reverse video in xterm:

               o   The command-line  -rv  option  tells  the  X  libraries  to
                   reverse  the  foreground  and  background  colors.  Xterm's
                   command-line options set resource values.   In  particular,
                   the  X  Toolkit sets the reverseVideo resource when the -rv
                   option is used.

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

               o   After startup, the user  can  toggle  the  "Enable  Reverse
                   Video"  menu  entry.  This exchanges the current foreground
                   and background colors of the VT100 widget, and repaints the
                   screen.    Because   of   the  X  resource  hierarchy,  the
                   reverseVideo  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"
                   feature),   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 width of the scrollbar border.  Note that this is
               drawn to overlap the border of the xterm window.  Modifying the
               scrollbar's  border  affects  only  the  line between the VT100
               widget and the scrollbar.  The default value is 1.

       scrollKey (class ScrollCond)
               Specifies whether or not pressing a  key  should  automatically
               cause  the  scrollbar  to  go  to  the  bottom of the scrolling
               region.  This corresponds to xterm's private  mode  1011.   The
               default is "false."

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

       scrollTtyOutput (class ScrollCond)
               Specifies  whether  or  not  output  to  the  terminal   should
               automatically  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
               window.  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
               default is "false."

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

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

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

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

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

               0    Set window/icon labels using hexadecimal

               1    Query window/icon labels using hexadecimal

               2    Set  window/icon  labels using UTF-8 (overrides 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
               underlining  when  color  is  being  used  for  the   underline
               attribute.  The default is "true."

       useClipping (class UseClipping)
               Tell  xterm whether to use clipping to keep from producing dots
               outside the text drawing area.  Originally used to work  around
               for overstriking effects, this is also needed to work with some
               incorrectly-sized fonts.  The default is "true."

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

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

               false (0)
                  UTF-8 mode is initially off.  The  command-line  option  +u8
                  sets  the  resource  to  this  value.   Escape sequences for
                  turning 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
               patterns 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,
                      allowing 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,
                      according to the effective value of the utf8 resource.

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

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

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

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

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

               The default is "false."

       veryBoldColors (class VeryBoldColors)
               Specifies  whether  to  combine  video  attributes  with colors
               specified  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
               character escape sequences while in UTF-8 mode.  The default is
               "true", to provide support for various legacy applications.

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

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

       wideFont (class WideFont)
               This  option  specifies the font to be used for displaying wide
               text.  By default, it will attempt to use a font twice as  wide
               as  the  font  that  will  be  used to draw normal text.  If no
               double-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.

               Specifies  what  character(s)  should  follow  a  GIN report or
               status report.  The possibilities are "none,"  which  sends  no
               terminating characters, "CRonly," which sends CR, and "CR&EOT,"
               which sends both CR and EOT.  The default is "none."

               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.

POINTER USAGE

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

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

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

              -  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/button 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
       command  to  the  shell, for example, or take output from a program and
       insert it into your favorite editor.  Since cut  buffers  are  globally
       shared  among  different  applications, you may regard each as a "file"
       whose contents you know.  The terminal emulator and other text programs
       should  be  treating  it  as  if it were a text file, i.e., the text is
       delimited by new lines.

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

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

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

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

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

SELECT/PASTE

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

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

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

   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
       receiving 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-
                   character support, it both accepts and provides this type.

              TEXT the text is in  the  encoding  which  corresponds  to  your
                   current 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
       configured with the i18nSelections resource set to "true".

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

       You can alter the types which xterm tries using the eightBitSelectTypes
       or  utf8SelectTypes  resources.   For  instance,  you  might  have some
       specific 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
                     passwords  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
                     environments.

       Commands for capturing output:

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

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

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

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

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

       Modes for setting keyboard style:

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

              Backarrow Key (BS/DEL) (backarrow key)
                     Modifies the behavior of the  backarrow  key,  making  it
                     transmit   either   a   backspace  (8)  or  delete  (127)
                     character.   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-
                     character  sequence with the character itself preceded by
                     ESC.  This corresponds to the metaSendsEscape resource.

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

              Old Function-Keys (oldFunctionKeys)

              HP Function-Keys (hpFunctionKeys)

              SCO Function-Keys (scoFunctionKeys)

              Sun Function-Keys (sunFunctionKeys)

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

       Commands for process signalling:

              Send STOP Signal (suspend)

              Send CONT Signal (continue)

              Send INT Signal (interrupt)

              Send HUP Signal (hangup)

              Send TERM Signal (terminate)

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

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

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

       VT102/VT220 Modes:

              Enable 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
                     corresponds  to  the appcursorDefault resource.  There is
                     no corresponding command-line option.

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

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

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

              Scroll to Bottom on Tty Output (scrollttyoutput)
                     Enable  (or  disable)  scrolling  to  the  bottom  of the
                     scrolling  region  on  output  to  the  terminal.    This
                     corresponds  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
                     keepSelection  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
                     Control-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
                     document Xterm Control Sequences).  The  menu  entry  and
                     the  escape  sequence  states  are  XOR'd:  if  both  are
                     enabled, the cursor  will  not  blink,  if  only  one  is
                     enabled, the cursor will blink.

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

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

       VT102/VT220 Commands:

              Do Soft Reset (softreset)
                     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
                     corresponds 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
                     window.

              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
       window, 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
       alternatives:

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

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

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

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

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

              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
                     characters.  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
                     characters.

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

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

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

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

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

                     Initially the checkmark is set according to both the utf8
                     and utf8Fonts resource values.  If the latter is  set  to
                     "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
                     terminal's notion of its function-key strings, as termcap
                     or   terminfo  capabilities.   This  corresponds  to  the
                     allowTcapOps resource.

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

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

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

              Large Characters (tektextlarge)

              #2 Size Characters (tektext2)

              #3 Size Characters (tektext3)

              Small Characters (tektextsmall)

       Commands:

              PAGE (tekpage)
                     Clear the Tektronix window.

              RESET (tekreset)

              COPY (tekcopy)

       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
       services of the X protocol to snoop  on  your  activities,  potentially
       capturing  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
       allowSendEvents 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
       particular concern when you  want  to  type  in  a  password  or  other
       sensitive  data.   The best solution to this problem is to use a better
       authorization 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
       displays a prompt before asking for the password, it is safest to enter
       secure mode before the prompt gets displayed, and to make sure that the
       prompt  gets  displayed  correctly (in the new colors), to minimize the
       probability of spoofing.  You can also bring up the menu again and make
       sure that a check mark appears next to the entry.

       Secure  Keyboard  mode  will  be  disabled  automatically if your xterm
       window becomes iconified (or otherwise unmapped), or if you start up  a
       reparenting window manager (that places a title bar or other decoration
       around the window) while in Secure Keyboard mode.  (This is  a  feature
       of  the  X  protocol  not  easily  overcome.)   When  this happens, the
       foreground and background colors will be switched  back  and  the  bell
       will sound in warning.

CHARACTER CLASSES

       Clicking  the  left  pointer  button twice in rapid succession (double-
       clicking) causes all characters of the same class (e.g., letters, white
       space, punctuation) to be selected as a "word".  Since different people
       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 */
               32,   1,   1,   1,   1,   1,   1,   1,

       For example, the string "33:48,37:48,45-47:48,38:48" indicates that the
       exclamation  mark,  percent  sign,  dash,  period, slash, and ampersand
       characters should be treated the same way as  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
       unpredictable 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.

       bell([percent])
               This action rings the keyboard bell at the specified percentage
               above or below the base volume.

       clear-saved-lines()
               This action does hard-reset() (see below) and also  clears  the
               history  of  lines saved off the top of the screen.  It is also
               invoked from the clearsavedlines entry in vtMenu.   The  effect
               is identical to a hardware reset (RIS) control sequence.

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

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

       dabbrev-expand()
               Expands the word before cursor by searching  in  the  preceding
               text  on  the  screen  and  in  the scrollback buffer for words
               starting with that  abbreviation.   Repeating  dabbrev-expand()
               several times in sequence searches for an alternative expansion
               by looking farther back.  Lack of more matches is signaled by a
               beep().  Attempts to expand an empty word (i.e., when cursor is
               preceded by a space) yield  successively  all  previous  words.
               Consecutive identical expansions are ignored.  The word here is
               defined as  a  sequence  of  non-whitespace  characters.   This
               feature   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
               echoing 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
               position escape sequences.

       insert()
               This action inserts the character or string associated with the
               key that was pressed.

       insert-eight-bit()
               This   action  inserts  an  eight-bit  (Meta)  version  of  the
               character or string associated with the key that  was  pressed.
               This  only  applies  to  single-byte  values.  The exact action
               depends  on  the  value  of   the   metaSendsEscape   and   the
               eightBitInput   resources.   The  metaSendsEscape  resource  is
               tested first.

               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
               cutbuffer  indicated by sourcename.  Sources are checked in the
               order  given  (case  is  significant)  until  one   is   found.
               Commonly-used   selections  include:  PRIMARY,  SECONDARY,  and
               CLIPBOARD.  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
               significant).   The name None restores the original translation
               table.

       larger-vt-font()
               Set the font  to  the  next  larger  one,  based  on  the  font
               dimensions.  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
               wideBoldFont.

       maximize()
               Resizes the window to fill the screen.

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

       popup-menu(menuname)
               This  action  displays  the  specified popup menu.  Valid names
               (case is significant) include:  mainMenu, vtMenu, fontMenu, and
               tekMenu.

       print(printer-flags)
               This  action prints the window and is also invoked by the print
               entry in mainMenu.

               The  action  accepts  optional  parameters,  which  temporarily
               override  resource  settings.  The parameter values are matched
               ignoring case:

               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
                    newline) to the  screen  width  (i.e.,  printerNewLine  is
                    ``true'').

               noAttrs
                    the    page   is   printed   without   attributes   (i.e.,
                    printAttributes 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
               printerCommand  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
               printOptsXError 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.

       quit()  This  action sends a SIGHUP to the subprogram and exits.  It is
               also invoked by the quit entry in mainMenu.

       readline-button()
               Supports the optional  readline  feature  by  echoing  repeated
               cursor  forward or backward control sequences on button release
               event, to request that the host application update  its  notion
               of the cursor's position to match the button event.

       redraw()
               This  action  redraws  the  window  and  is also invoked by the
               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
               visible.

               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 is similar to scroll-back except that it scrolls in
               the other direction.

       secure()
               This  action  toggles the Secure Keyboard mode described in the
               section named SECURITY, and is invoked from the securekbd entry
               in mainMenu.

       scroll-lock(on/off/toggle)
               This  action  toggles  internal state which tells xterm whether
               Scroll Lock is active, subject to the allowScrollLock resource.

       select-cursor-end(destname [, ...])
               This action is similar to select-end except that it  should  be
               used with select-cursor-start.

       select-cursor-extend()
               This  action  is similar to select-extend except that it should
               be used with select-cursor-start.

       select-cursor-start()
               This action is similar to select-start except  that  it  begins
               the selection at the current text cursor position.

       select-end(destname [, ...])
               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.

       select-set()
               This  action  stores  text  that  corresponds  to  the  current
               selection, without affecting the selection mode.

       select-start()
               This action  begins  text  selection  at  the  current  pointer
               location.   See the section on POINTER USAGE for information on
               making selections.

       send-signal(signame)
               This action sends the signal named  by  signame  to  the  xterm
               subprocess  (the shell or program specified with the -e command
               line option) and is also  invoked  by  the  suspend,  continue,
               interrupt,  hangup,  terminate,  and  kill entries in mainMenu.
               Allowable signal names are (case is not significant): tstp  (if
               supported  by  the  operating  system), suspend (same as tstp),
               cont (if supported by the operating system),  int,  hup,  term,
               quit, alrm, alarm (same as alrm) and kill.

       set-8-bit-control(on/off/toggle)
               This  action  toggles  the eightBitControl resource and is also
               invoked from the 8-bit-control entry in vtMenu.

       set-allow132(on/off/toggle)
               This action toggles the c132 resource and is also invoked  from
               the allow132 entry in vtMenu.

       set-altscreen(on/off/toggle)
               This action toggles between the alternate and current screens.

       set-appcursor(on/off/toggle)
               This  action  toggles  the handling Application Cursor Key mode
               and is also invoked by the appcursor entry in vtMenu.

       set-appkeypad(on/off/toggle)
               This action toggles the handling of Application Keypad mode and
               is also invoked by the appkeypad entry in vtMenu.

       set-autolinefeed(on/off/toggle)
               This  action  toggles  automatic  insertion of linefeeds and is
               also invoked by the autolinefeed entry in vtMenu.

       set-autowrap(on/off/toggle)
               This action toggles automatic wrapping of  long  lines  and  is
               also invoked by the autowrap entry in vtMenu.

       set-backarrow(on/off/toggle)
               This  action  toggles  the  backarrowKey  resource  and is also
               invoked from the backarrow key entry in vtMenu.

               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

               s or S indicate the font selection (as made by programs such as
                      xfontsel(1)) indicated by the second action argument.

               If  xterm  is  configured  to  support  wide   characters,   an
               additional  two  optional  parameters  are recognized for the e
               argument: wide font and wide bold font.

       smaller-vt-font()
               Set the font to  the  next  smaller  one,  based  on  the  font
               dimensions.  See also set-vt-font().

       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
               selection is extended to the current pointer location.

       start-cursor-extend()
               This  action  is  similar  to  select-extend  except  that  the
               selection 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
               whitespace  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
               current  window  contents  to  a  file in the current directory
               beginning 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
               echoing a control  sequence  computed  from  the  event's  line
               number in the screen relative to the current line:

                       ESC ^P
               or
                       ESC ^N

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

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

       The Tektronix window also has the following action:

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

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

                     Shift <KeyPress> Prior:scroll-back(1,halfpage) \n\
                      Shift <KeyPress> Next:scroll-forw(1,halfpage) \n\

                                  <BtnDown>:ignore()

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

                                 <Btn5Down>: StartScroll(Forward) \n\
                                 <Btn1Down>: StartScroll(Forward) \n\
                                 <Btn2Down>: StartScroll(Continuous) MoveThumb() NotifyThumb() \n\
                                 <Btn3Down>: StartScroll(Backward) \n\

                                 <Btn2Motion>: MoveThumb() NotifyThumb() \n\
                                 <BtnUp>:    NotifyScroll(Proportional) EndScroll()

       The default bindings in the Tektronix window are:

                            ~Meta<KeyPress>: insert-seven-bit() \n\
                             Meta<KeyPress>: insert-eight-bit() \n\
                           !Ctrl <Btn1Down>: popup-menu(mainMenu) \n\
                      !Lock Ctrl <Btn1Down>: popup-menu(mainMenu) \n\
            !Lock Ctrl @Num_Lock <Btn1Down>: popup-menu(mainMenu) \n\
                 !Ctrl @Num_Lock <Btn1Down>: popup-menu(mainMenu) \n\

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

       Here  is  an  example  which  uses  shifted select/paste to copy to the
       clipboard, 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
       corresponding 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: \

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

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

CONTROL SEQUENCES AND KEYBOARD

       The Xterm Control Sequences document lists the control sequences  which
       an  application  can  send xterm to make it perform various operations.
       Most of these operations are  standardized,  from  either  the  DEC  or
       Tektronix  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
            necessarily 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
       following:

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

       HOME when xterm is configured to update utmp.

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

       LOGNAME
            when xterm is configured to update utmp.

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

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

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

FILES

       The actual pathnames given may differ on your system.

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

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

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

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

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

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.
