The key sequences to which individual commands are bound can be changed, and key bindings can be set up for commands which are not, by default, bound to any key sequences. Interactive means of modifying key bindings are described in Key bindings.
This section describes the editor function
bind-key
, which is used to establish bindings programmatically. If you want to alter your personal key bindings, put the modifying code in your
.lispworks
file.
The default Emacs key bindings can be found in the file
config/key-binds.lisp
in the LispWorks library directory. See Key bindingsfor details of the key binds files used in other editor emulations.
editor:bind-key
name
key
&optional
kind
where
Binds the command name to the key sequence or combination key .
kind
can take the value
:global
,
:mode
, or
:buffer
.
The default for
kind
is
:global
. which makes the binding apply in all buffers and all modes, unless overridden by a mode-specific or buffer-specific binding.
If
where
is not supplied, the binding is for the current emulation. Otherwise
where
should be either
:emacs
or
:pc
, meaning that the binding is for Emacs emulation or Microsoft Windows emulation respectively.
Note: before the editor starts, the current emulation is
:emacs
. Therefore
bind-key
forms which do not specify
where
and which are evaluated before the editor starts (for example, in your initialization file) will apply to Emacs emulation only. Thus for example
(bind-key "Command" "Control-Right")
when evaluated in your initialization file will establish an Emacs emulation binding. The same form when evaluated after editor startup will establish a binding in the current emulation: Emacs or Microsoft Windows emulation.
It is best to specify the intended emulation:
(editor:bind-key "Command" "Control-Right" :global :pc)
If
kind
is
:buffer
the binding applies only to a buffer which should be specified by the value of
where
.
If
kind
is
:mode
the binding applies only to a mode which should be specified by
where
.
If this function is called interactively via the command Bind Key, you will be prompted as necessary for the kind of binding, the buffer or the mode. The binding is for the current emulation.
Tab
completion may be used at any stage.
The following examples, which are used to implement some existing key bindings, illustrate how key sequences can be specified using
bind-key
.
(editor:bind-key "Forward Character" #\control-\f)
(editor:bind-key "Forward Word" #\meta-\f)
(editor:bind-key "Save File" '#(#\control-\x #\control-\s))
(editor:bind-key "Regexp Forward Search" #\meta-control-\s)
(editor:bind-key "Complete Field" #\space :mode "Echo Area")
(editor:bind-key "Backward Character" "left")
(editor:bind-key "Forward Word" #("control-right"))
editor:bind-string-to-key
string
key
&optional
kind
where
Binds the text string
string
to the keyboard shortcut
key
without the need to create a command explicitly. Using
key
inserts
string
in the current buffer. The
kind
and
where
arguments are as for
editor:bind-key
.
editor:set-interrupt-keys
keys
&optional
input-style
The key that aborts the current editor command is handled specially by the editor. If you wish to change the default (from
Ctrl+G
for Emacs) then you must use this function rather than
editor:bind-key
. See the file
config\msw-key-binds.lisp
for an example.
