 NAME
      xterm - terminal emulator for X

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

 DESCRIPTION
      The xterm program is a terminal emulator for the X Window System.	 It
      provides DEC VT102 and Tektronix 4014 compatible terminals for
      programs that can't 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 VT102 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 VT102 window, and the ``Tek Options'' menu in
      the 4014 window.

 EMULATIONS
      The VT102 emulation is fairly complete, but does not support smooth
      scrolling, VT52 mode, the blinking character attribute nor the
      double-wide and double-size character sets.  Termcap(5) entries that
      work with xterm include ``xterm,'' ``vt102,'' ``vt100'' and ``ansi,''
      and xterm automatically searches the termcap file in this order for
      these entries and then sets the ``TERM'' and the ``TERMCAP''
      environment variables.

      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
      ``COPYyy-MM-dd.hh:mm:ss'', where yy, MM, dd, hh, mm and ss are the
      year, month, day, hour, minute and second when the COPY was performed

				 Release 6.3



      (the file is created in the directory xterm is started in, or the home
      directory for a login xterm).

 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.

      In either VT102 or Tektronix mode, there are escape sequences to
      change the name of the windows.  See Xterm Control Sequences for
      details.

 OPTIONS
      The xterm terminal emulator accepts all of the standard X Toolkit
      command line options as well as the following (if the option begins
      with a `+' instead of a `-', the option is restored to its default
      value):

      -help   This causes xterm to print out a verbose message describing
	      its options.

      -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.

      -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.	 The default is 2.

      -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.

      -cn     This option indicates that newlines should not be cut in
	      line-mode selections.

      +cn     This option indicates that newlines should be cut in line-mode
	      selections.

      -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.

      -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.

      -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.

      -fb font
	      This option specifies a font to be used when displaying bold
	      text. This font must be the same height and width as the
	      normal font.  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.	The default
	      is to do overstriking of the normal font.

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

      -im     Turn on the useInsertMode resource.

      +im     Turn off the useInsertMode resource.

      -j      This option indicates that xterm should do jump scrolling.
	      Normally, text is scrolled one line at a time; this option
	      allows xterm to move multiple lines at a time so that it
	      doesn't fall as far behind.  Its use is strongly recommended
	      since it make 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.

      -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).

      +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.	 This option
	      can be turned on and off from the ``VT Options'' menu.

      +mb     This option indicates that margin bell should not be rung.

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

      -ms color
	      This option specifies the color to be used for the pointer
	      cursor.  The default is to use the foreground color.

      -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.

      -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.

      -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 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.

      -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.

      -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.

      -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.	The default is 64.

      -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.

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

      -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.  Allowable keywords
	      include: intr, quit, erase, kill, eof, eol, swtch, start,
	      stop, brk, susp, dsusp, rprnt, flush, weras, and lnext.
	      Control characters may be specified as ^char (e.g. ^c or ^u)
	      and ^? may be used to indicate delete.

      -tn name
	      This option specifies the name of the terminal type to be set
	      in the TERM environment variable.	 This terminal type must
	      exist in the termcap(5) database and should have li# and co#
	      entries.

      -ut     This option indicates that xterm shouldn't write a record into
	      the the system log file /etc/utmp.

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

      -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.

      -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 show not wait before starting
	      the subprocess.

      -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 specifies the last two letters of the name of a
	      pseudoterminal to use in slave mode, plus the number of the
	      inherited file descriptor.  The option is parsed ``%c%c%d''.
	      This allows xterm to be used as an input and output channel
	      for an existing program and is sometimes used in specialized
	      applications.

      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:

      -bg color
	      This option specifies the color to use for the background of
	      the window. The default is ``white.''

      -bd color
	      This option specifies the color to use for the border of the



				    - 7 -	  Formatted:  August 2, 2006

	      window.  The default is ``black.''

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

      -fg color
	      This option specifies the color to use for displaying text.
	      The default is ``black.''

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

      -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.

      -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.

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

      -geometry geometry
	      This option specifies the preferred size and position of the
	      VT102 window; see X(1).

      -display display
	      This option specifies the X server to contact; see X(1).

      -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.

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

 RESOURCES
      The program understands all of the core X Toolkit resource names and
      classes as well as:

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



				    - 8 -	  Formatted:  August 2, 2006






 XTERM(1)			X Version 11			    XTERM(1)
				 Release 6.3



	      managers.

      iconName (class IconName)
	      Specifies the icon name.	The default is the application name.

      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.

      ttyModes (class TtyModes)
	      Specifies a string containing terminal setting keywords and
	      the characters to which they may be bound.  Allowable keywords
	      include: intr, quit, erase, kill, eof, eol, swtch, start,
	      stop, brk, susp, dsusp, rprnt, flush, weras, and lnext.
	      Control characters may be specified as ^char (e.g. ^c or ^u)
	      and ^? may be used to indicate Delete.  This is very useful
	      for overriding the default terminal settings without having to
	      do an stty every time an xterm is started.

      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.''

      utmpInhibit (class UtmpInhibit)
	      Specifies whether or not xterm should try to record the user's
	      terminal in /etc/utmp.

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

      waitForMap (class WaitForMap)
	      Specifies whether or not xterm should wait for the initial
	      window map before starting the subprocess.  The default is
	      ``false.''


      The following resources are specified as part of the vt100 widget
      (class VT100):

      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



				    - 9 -	  Formatted:  August 2, 2006






 XTERM(1)			X Version 11			    XTERM(1)
				 Release 6.3



	      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.''

      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 creates a
	      very large security hole.


      alwaysHighlight (class AlwaysHighlight)
	      Specifies whether or not xterm should always display a
	      highlighted text cursor.	By default, a hollow text cursor is
	      displayed whenever the pointer moves out of the window or the
	      window loses the input focus.

      appcursorDefault (class AppcursorDefault)
	      If ``true,'' the cursor keys are initially in application
	      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.
	      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.

      boldFont (class BoldFont)
	      Specifies the name of the bold font to use instead of
	      overstriking.

	      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

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

      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.  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.  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 the cut buffer is globally
      shared among different applications, you should regard it 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.

      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.

				 Release 6.3



      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.

      Unlike the VT102 window, the Tektronix window dows 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).

 MENUS
      Xterm has four menus, named mainMenu, vtMenu, fontMenu, and tekMenu.
      Each menu pops up under the correct combinations of key and button
      presses.	Most menus are divided into two section, separated by a
      horizontal line.	The top portion contains various 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.	The bottom
      portion of the menu are command entries; selecting one of these
      performs the indicated function.

      The xterm menu pops up when the ``control'' key and pointer button one
      are pressed in a window.	The mainMenu contains items that apply to
      both the VT102 and Tektronix windows.  The Secure Keyboard mode is be
      used when typing in passwords or other sensitive data in an unsecure
      environment; see SECURITY below.	Notable entries in the command
      section of the menu are the Continue, Suspend, Interrupt, Hangup,
      Terminate and Kill which sends the SIGCONT, SIGTSTP, SIGINT, SIGHUP,
      SIGTERM and SIGKILL signals, respectively, to the process group of the
      process running under xterm (usually the shell).	The Continue
      function is especially useful if the user has accidentally typed
      CTRL-Z, suspending the process.

      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.  In the command section of this menu, the soft reset
      entry will 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).  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.

      The fontMenu sets the font used in the VT102 window.  In addition to
      the default font and a number of alternatives that are set with
      resources, the menu offers the font last specified by the Set Font
      escape sequence (see the document Xterm Control Sequences) and the
      current selection as a font name (if the PRIMARY selection is owned).

      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.  The PAGE entry in the command section
      clears the Tektronix window.

 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, there is every possibility that someone can run an
      application that will use the basic services of the X protocol to
      snoop on your activities, potentially capturing a transcript of
      everything you type at the keyboard.  This 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
      that host-based control, but a simple mechanism exists for protecting
      keyboard input in xterm.

      The xterm menu (see MENUS above) contains a Secure Keyboard entry
      which, when enabled, ensures 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.  Only one X client at a
      time can secure 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

				 Release 6.3



      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 middle mouse button twice in rapid succession will cause
      all characters of the same class (e.g. letters, white space,
      punctuation) to be selected.  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
      127, corresponding to the ASCII 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.

      The default table is

	      static int charClass[128] = {
	      /* NUL  SOH  STX	ETX  EOT  ENQ  ACK  BEL */

      For example, the string ``33:48,37:48,45-47:48,64:48'' 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 for the vt100 or
      tek4014 widgets.	Changing the translations for events other than key
      and button events is not expected, and will cause unpredictable
      behavior.	 The following actions are provided for using within the
      vt100 or tek4014 translations resources:

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

      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-seven-bit()
	      This action is a synonym for insert()

      insert-eight-bit()
	      This action inserts an eight-bit (Meta) version of the
	      character or string associated with the key that was pressed.
	      The exact action depends on the value of the eightBitInput
	      resource.

      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.

      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

	      (case is significant) include:  mainMenu, vtMenu, fontMenu,
	      and tekMenu.

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

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

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

      select-end(destname [, ...])
	      This action puts the currently selected text into all of the
	      selections or cutbuffers specified by destname.

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

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

      set-vt-font(d/1/2/3/4/5/6/e/s [,normalfont [, boldfont]])
	      This action sets the font or fonts currently being used in the
	      VT102 window.  The first argument is a single character that
	      specifies the font to be used: d or D indicate the default
	      font (the font initially used when xterm was started), 1
	      through 6 indicate the fonts specified by the font1 through
	      font6 resources, e or E indicate the normal and bold fonts
	      that have been set through escape codes (or specified as the
	      second and third action arguments, respectively), and s or S
	      indicate the font selection (as made by programs such as
	      xfontsel(1)) indicated by the second action argument.

      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



				   - 25 -	  Formatted:  August 2, 2006

	      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.

      scroll-back(count [,units])
	      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.

      scroll-forw(count [,units])
	      This action scrolls is similar to scroll-back except that it
	      scrolls the other direction.

	      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.

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

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

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

 ENVIRONMENT
      Xterm sets the environment variables ``TERM'' and ``TERMCAP'' properly
      for the size window you have created.  It also uses and sets the
      environment variable ``DISPLAY'' to specify which bit map display
      terminal to use.	The environment variable ``WINDOWID'' is set to the
      X window id number of the xterm window.

 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.

      Only fixed-width, character-cell fonts are supported.

      This program still needs to be rewritten.	 It should be split into
      very modular sections, with the various emulators being completely
      separate widgets that don't 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.
