.SH DEFAULT KEY BINDINGS IN EMACS MODE

The following default key bindings, which can be overriden by
the tecla configuration file, are designed to mimic most of
the bindings of the unix \f3tcsh\f1 shell, when it is in
emacs editing mode.
.sp
This is the default editing mode of the tecla library.
.sp
Note that a key sequence like \f3^A\f1 or \f3C-a\f1 means hold the control-key
down while pressing the letter \f3A\f1, and that where you see \f3\\E\f1 or
\f3M-\f1 in a binding, this represents the escape key or the Meta modifier
key. Also note that to \f3gl_get_line()\f1, pressing the escape key before a
key is equivalent to pressing the meta key at the same time as that key. Thus
the key sequence \f3M-p\f1 can be typed in two ways, by pressing the escape
key, followed by pressing \f3p\f1, or by pressing the Meta key at the same time
as \f3p\f1.
.sp
Under UNIX the terminal driver sets a number of special keys for certain
functions. The tecla library attempts to use the same keybindings to maintain
consistency. The key sequences shown for the following 6 bindings are thus just
examples of what they will probably be set to. If you have used the \f3stty\f1
command to change these keys, then the default bindings should match.

.nf
  ^C     ->   user-interrupt
  ^\\     ->   abort
  ^Z     ->   suspend
  ^Q     ->   start-output
  ^S     ->   stop-output
  ^V     ->   literal-next
.fi

The cursor keys are refered to by name, as follows. This is necessary
because different types of terminals generate different key sequences
when their cursor keys are pressed.

  right  ->   cursor-right
  left   ->   cursor-left
  up     ->   up-history
  down   ->   down-history

The remaining bindings don't depend on the terminal setttings.

.nf
  ^F     ->   cursor-right
  ^B     ->   cursor-left
  M-i    ->   insert-mode
  ^A     ->   beginning-of-line
  ^E     ->   end-of-line
  ^U     ->   delete-line
  ^K     ->   kill-line
  M-f    ->   forward-word
  M-b    ->   backward-word
  ^D     ->   del-char-or-list-or-eof
  ^H     ->   backward-delete-char
  ^?     ->   backward-delete-char
  M-d    ->   forward-delete-word
  M-^H   ->   backward-delete-word
  M-^?   ->   backward-delete-word
  M-u    ->   upcase-word
  M-l    ->   downcase-word
  M-c    ->   capitalize-word
  ^R     ->   redisplay
  ^L     ->   clear-screen
  ^T     ->   transpose-chars
  ^@     ->   set-mark
  ^X^X   ->   exchange-point-and-mark
  ^W     ->   kill-region
  M-w    ->   copy-region-as-kill
  ^Y     ->   yank
  ^P     ->   up-history
  ^N     ->   down-history
  M-p    ->   history-search-backward
  M-n    ->   history-search-forward
  ^I     ->   complete-word
  ^X*    ->   expand-filename
  ^X^F   ->   read-from-file
  ^X^R   ->   read-init-files
  ^Xg    ->   list-glob
  ^Xh    ->   list-history
  M-<    ->   beginning-of-history
  M->    ->   end-of-history
  \\n     ->   newline
  \\r     ->   newline
  M-o    ->   repeat-history
  M-^V   ->   vi-mode

  M-0, M-1, ... M-9  ->  digit-argument  (see below)
.fi

Note that ^I is what the TAB key generates, and that ^@ can be
generated not only by pressing the control key and the @ key
simultaneously, but also by pressing the control key and the space bar
at the same time.

.SH DEFAULT KEY BINDINGS IN VI MODE

The following default key bindings are designed to mimic the
vi style of editing as closely as possible. This means that
very few editing functions are provided in the initial
character input mode, editing functions instead being
provided by the vi command mode. Vi command mode is entered
whenever the escape character is pressed, or whenever a
key-sequence that starts with a meta character is entered. In
addition to mimicing vi, libtecla provides bindings for tab
completion, wild-card expansion of file names, and historical
line recall.
.sp
To learn how to tell the tecla library to use vi mode instead
of the default emacs editing mode, see the section entitled
THE TECLA CONFIGURATION FILE.
.sp
As already mentioned above in the emacs section, Note that a
key sequence like \f3^A\f1 or \f3C-a\f1 means hold the
control-key down while pressing the letter \f3A\f1, and that
where you see \f3\\E\f1 or \f3M-\f1 in a binding, this
represents the escape key or the Meta modifier key. Also note
that to \f3gl_get_line()\f1, pressing the escape key before a
key is equivalent to pressing the meta key at the same time
as that key. Thus the key sequence \f3M-p\f1 can be typed in
two ways, by pressing the escape key, followed by pressing
\f3p\f1, or by pressing the Meta key at the same time as
\f3p\f1.
.sp
Under UNIX the terminal driver sets a number of special keys
for certain functions. The tecla library attempts to use the
same keybindings to maintain consistency, binding them both
in input mode and in command mode. The key sequences shown
for the following 6 bindings are thus just examples of what
they will probably be set to. If you have used the \f3stty\f1
command to change these keys, then the default bindings
should match.

.nf
  ^C     ->   user-interrupt
  ^\\     ->   abort
  ^Z     ->   suspend
  ^Q     ->   start-output
  ^S     ->   stop-output
