VMS freeware XTERM
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:
allow-send-events(on/off/toggle)
This action set or toggles the allowSendEvents resource and is also
invoked by the allowsends entry in mainMenu.
bell([percent])
This action rings the keyboard bell at the specified percentage
above or below the base volume.
clear-saved-lines()
This action does hard-reset() (see above) and also clears the
history of lines saved off the top of the screen. It is also
invoked from the clearsavedlines entry in vtMenu.
create-menu(m/v/f/t)
This action creates one of the menus used by xterm, if it has not
been previously created. The parameter values are the menu names:
mainMenu, vtMenu, fontMenu, tekMenu, respectively.
deiconify()
Changes the window state back to normal, if it was iconified.
dired-button()
Handles a button event (other than press and release) by echoing
the event's position (i.e., character line and column) in the fol-
lowing format:
^X ESC G <line+' '> <col+' '>
iconify()
Iconifies the window.
hard-reset()
This action resets the scrolling region, tabs, window size, and
cursor keys and clears the screen. It is also invoked from the
hardreset entry in vtMenu.
ignore()
This action ignores the event but checks for special pointer posi-
tion escape sequences.
insert()
This action inserts the character or string associated with the key
that was pressed.
insert-eight-bit()
This action inserts an eight-bit (Meta) version of the character or
string associated with the key that was pressed. The exact action
depends on the value of the metaSendsEscape and the eightBitInput
resources.
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 typi-
cally named CUT_BUFFER0 through CUT_BUFFER7.
insert-seven-bit()
This action is a synonym for insert()
interpret(control-sequence)
Interpret the given control sequence locally, i.e., without passing
it to the host. This works by inserting the control sequence at
the front of the input buffer. Use "\" to escape octal digits in
the string. Xt does not allow you to put a null character (i.e.,
"\000") in the string.
keymap(name)
This action dynamically defines a new translation table whose
resource name is name with the suffix Keymap (case is significant).
The name None restores the original translation table.
maximize()

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

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

entry in mainMenu.
restore()
Restores the window to the size before it was last maximized.
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.
secure()
This action toggles the Secure Keyboard mode described in the sec-
tion named SECURITY, and is invoked from the securekbd entry in
mainMenu.
select-cursor-end(destname [, ...])
This action is similar to select-end except that it should be used
with select-cursor-start.
select-cursor-start()
This action is similar to select-start except that it begins the
selection at the current text cursor position.
select-end(destname [, ...])
This action puts the currently selected text into all of the selec-
tions or cutbuffers specified by destname.
select-extend()
This action tracks the pointer and extends the selection. It
should only be bound to Motion events.
select-set()
This action stores text that corresponds to the current selection,
without affecting the selection mode.
select-start()
This action begins text selection at the current pointer location.
See the section on POINTER USAGE for information on making selec-
tions.
