XTERM(1)                                                 XTERM(1)


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 compati-
       ble  terminals for programs that can't use the window sys-
       tem 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 when-
       ever 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 graph-
       ics in the other at the same time.  To maintain  the  cor-
       rect  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  sup-
       port  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 (like logging)  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.  Four
       different font sizes and five different  lines  types  are
       supported.   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 Tek-
       tronix 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 (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  high-
       lighted 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  alter-
       nate  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 and to specify
       a  new  log  file  name.   See Xterm Control Sequences for
       details.  Enabling the escape sequence to change  the  log
       file name is a compile-time option; by default this escape
       sequence is ignored for security reasons.

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.

       -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 curses(3x) cursor motion pack-
               age  that  causes  the  more(1) program to display
               lines that are exactly the width of the window and
               are  followed by a line beginning with a tab to be
               displayed incorrectly (the leading  tabs  are  not
               displayed).

       +cu     This  option  indicates that that xterm should not
               work around the curses(3x) bug mentioned above.

       -e program ...]
               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 dis-
               playing 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.

       -im     Turn on the useInsertMode resource.



X Version 11                Release 5                           3




XTERM(1)                                                 XTERM(1)


       +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.

       -l      This option indicates that xterm should  send  all
               terminal  output  to  a log file as well as to the
               screen.  This option can be  enabled  or  disabled
               using the ``VT Options'' menu.

       +l      This  option  indicates  that  xterm should not do
               logging.

       -lf filename
               This option specifies the  name  of  the  file  to
               which  the  output log described above is written.
               If file begins with a pipe symbol (|), the rest of
               the  string  is assumed to be a command to be used
               as the endpoint of a pipe.  The ability to log  to
               a  pipe is a compile-time option which is disabled
               by default  for  security  reasons.   The  default
               filename is ``XtermLog.XXXXX'' (where XXXXX is the
               process id of xterm) and is created in the  direc-
               tory  from  which xterm was started (or the user's
               home directory in the case of a login window).

       -ls     This option  indicates  that  the  shell  that  is
               started in the xterm window 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.

XTERM(1)                                                 XTERM(1)


       -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  fore-
               ground 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 automati-
               cally 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 asyn-
               chronously, 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.

XTERM(1)                                                 XTERM(1)


       -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 pro-
               gram.  Allowable  keywords  include:  intr,  quit,
               erase,  kill,  eof,  eol, swtch, start, stop, brk,
               susp, dsusp, rprnt, flush, weras, and lnext.  Con-
               trol 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.

XTERM(1)                                                 XTERM(1)


       -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 pre-
               ferred 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 termi-
               nal 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 pro-
               grams explicitly change the ownership of the  con-
               sole 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 com-
       patibility 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 posi-
               tion 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.

XTERM(1)                                                 XTERM(1)


       -T string
               This option specifies the title for  xterm's  win-
               dows.  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  back-
               ground 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 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  dis-
               playing text.  The default is ``black.''

       -fn font
               This option specifies the font to be used for dis-
               playing 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

XTERM(1)                                                 XTERM(1)


               line specified after the -e option, if any, other-
               wise the application name.

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

       -geometry geometry
               This option specifies the preferred size and posi-
               tion 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 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.  Con-
               trol characters may be specified as ^char (e.g. ^c
               or ^u) and ^? may  be  used  to  indicate  Delete.



X Version 11                Release 5                           9




XTERM(1)                                                 XTERM(1)


               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):

       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 dis-
               play 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 sup-
               pressed.  Default is 200.  If set non-zero,  addi-
               tional  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.

       c132 (class C132)
               Specifies  whether or not the VT102 DECCOLM escape
               sequence  should  be  honored.   The  default   is
               ``false.''

       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.''

       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.''

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

       curses (class Curses)
               Specifies  whether  or  not the last column bug in
               curses(3x) should be worked around.   The  default
               is ``false.''

       background (class Background)
               Specifies  the  color to use for the background of
               the window.  The default is ``white.''

       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 ``black.''

               Specifies the color to use for  the  text  cursor.
               The default is ``black.''

       eightBitInput (class EightBitInput)
               If  true,  Meta characters input from the keyboard
               are presented  as  a  single  character  with  the
               eighth  bit  turned on.  If false, Meta characters
               are converted into a two-character  sequence  with
               the character itself preceded by ESC.  The default
               is ``true.''

       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.''

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

               ters and the window border.  The default is 2.

       jumpScroll (class JumpScroll)
               Specifies  whether  or  not  jump scroll should be
               used.  The default is ``true.''

               Specifies the name of the file to which a terminal
               session     is    logged.     The    default    is

               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.

               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)

               screen-oriented programs) from the TERMCAP string.
               If  set, xterm also ignores the escape sequence to
               switch to the alternate screen.

       translations (class Translations)
               Specifies the key and button bindings  for  menus,
               selections,   ``programmed  strings,''  etc.   See
               ACTIONS below.

       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.''


       The  following  resources  are  specified  as  part of the

               ``none,'' which sends no  terminating  characters,
               ``CRonly,''  which sends CR, and ``CR&EOT,'' which
               sends both CR and EOT.  The default is ``none.''

       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.

       The  selection functions are invoked when the pointer but-
       tons 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 cur-
       sor 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.




X Version 11                Release 5                          20




XTERM(1)                                                 XTERM(1)


       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 selec-
       tion 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.

       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 but-
       ton  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).

XTERM(1)                                                 XTERM(1)


MENUS
       Xterm  has  four  menus, named mainMenu, vtMenu, fontMenu,
       and tekMenu.  Each menu pops up under the correct combina-
       tions  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 envi-
       ronment; see SECURITY below.  Notable entries in the  com-
       mand section of the menu are the Continue, Suspend, Inter-
       rupt, 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 sec-
       tion 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 pro-
       cessing 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  docu-
       ment 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 but-
       ton 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.

       cookie''  authorization  scheme that can provide a reason-
       able 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 key-
       board.  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  Key-
       board 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 dis-
       able 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 suc-
       ceeds,  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  hap-
       pens,   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

       CharClass) resource.

       This  resource is simply a list of range:value pairs where
       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  arbi-
       trary,  although the default table uses the character num-
       ber of the first character occurring in the set.

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 transla-
       tions for events other than key and button events  is  not
       expected, and will cause unpredictable behavior.  The fol-
       lowing actions are provided for using within the vt100  or
       tek4014 translations resources:

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

       ignore()
               This action ignores the event but checks for  spe-
               cial pointer position escape sequences.

       insert()
               This  action inserts the character or string asso-
               ciated 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 selec-
               tion  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 CLIP-
               BOARD.    Cut   buffers   are   typically    named
               CUTBUFFER0 through CUTBUFFER7.

       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.

       popup-menu(menuname)
               This action displays  the  specified  popup  menu.
               Valid  names (case is significant) include:  main-
               Menu, 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.

XTERM(1)                                                 XTERM(1)


       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 nor-
               mal and bold fonts  that  have  been  set  through
               escape codes (or specified as the second and third
               action arguments, respectively), and s or S  indi-
               cate  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 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

               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.

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

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

       redraw()

               by the redraw entry in mainMenu.

       send-signal(signame)
               This  action  sends the signal named by signame to
               the xterm subprocess (the shell or program  speci-
               fied  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  signifi-
               cant):  tstp  (if  supported by the operating sys-
               tem), suspend (same as tstp), cont  (if  supported
               by  the  operating  system), int, hup, term, quit,
               alrm, alarm (same as alrm) and kill.

XTERM(1)                                                 XTERM(1)


       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 are:

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

                                    select-cursor-end(PRIMARY, CUT_BUFFER0) \n\
           Shift <KeyPress> Insert: insert-selection(PRIMARY, CUT_BUFFER0) \n\
                   ~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\
                  ~Meta <Btn1Down>: select-start() \n\

                         <BtnDown>: bell(0)


       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\
                !Ctrl <Btn2Down>:   popup-menu(tekMenu) \n\
           !Lock Ctrl <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\

                 ~Meta<Btn3Down>:   gin-press(r)


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

           *VT100.Translations: #override <Key>F13: keymap(dbx)
           *VT100.dbxKeymap.translations: \
                <Key>F14: keymap(None) \n\
                <Key>F17: string("next") string(0x0d) \n\

                <Key>F20: string("print ") insert-selection(PRIMARY, CUT_BUFFER0)


ENVIRONMENT
       Xterm  sets the environment variables ``TERM'' and ``TERM-
       CAP'' 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  envi-
       ronment  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.

       The Tek widget does not support key/button re-binding.

       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 emula-
       tors 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 log file
       name and the COPY file name.
