;;; Commentary:
|
||
|
||
;;; Usage:
|
||
;;
|
||
;; The `C-x C-k' (`edit-kbd-macro') command edits a keyboard macro
|
||
;; in a special buffer. It prompts you to type a key sequence,
|
||
;; which should be one of:
|
||
;;
|
||
;; * RET or `C-x e' (call-last-kbd-macro), to edit the most
|
||
;; recently defined keyboard macro.
|
||
;;
|
||
;; * `M-x' followed by a command name, to edit a named command
|
||
;; whose definition is a keyboard macro.
|
||
;;
|
||
;; * `C-h l' (view-lossage), to edit the 100 most recent keystrokes
|
||
;; and install them as the "current" macro.
|
||
;;
|
||
;; * any key sequence whose definition is a keyboard macro.
|
||
;;
|
||
;; This file includes a version of `insert-kbd-macro' that uses the
|
||
;; more readable format defined by these routines.
|
||
;;
|
||
;; Also, the `read-kbd-macro' command parses the region as
|
||
;; a keyboard macro, and installs it as the "current" macro.
|
||
;; This and `format-kbd-macro' can also be called directly as
|
||
;; Lisp functions.
|
||
|
||
;; Type `C-h m', or see the documentation for `edmacro-mode' below,
|
||
;; for information about the format of written keyboard macros.
|
||
|
||
;; `edit-kbd-macro' formats the macro with one command per line,
|
||
;; including the command names as comments on the right. If the
|
||
;; formatter gets confused about which keymap was used for the
|
||
;; characters, the command-name comments will be wrong but that
|
||
;; won't hurt anything.
|
||
|
||
;; With a prefix argument, `edit-kbd-macro' will format the
|
||
;; macro in a more concise way that omits the comments.
|
||
|
||
;; This package requires GNU Emacs 19 or later, and daveg's CL
|
||
;; package 2.02 or later. (CL 2.02 comes standard starting with

To abort the edit, just kill this buffer with \\[kill-buffer] RET.

Press \\[edmacro-insert-key] to insert the name of any key by typing the key.
|
||
|
||
The editing buffer contains a \"Command:\" line and any number of
|
||
\"Key:\" lines at the top. These are followed by a \"Macro:\" line
|
||
and the macro itself as spelled-out keystrokes: `C-x C-f foo RET'.
|
||
|
||
The \"Command:\" line specifies the command name to which the macro
|
||
is bound, or \"none\" for no command name. Write \"last-kbd-macro\"
|
||
to refer to the current keyboard macro (as used by \\[call-last-kbd-macro]).
|
||
|
||
The \"Key:\" lines specify key sequences to which the macro is bound,
|
||
or \"none\" for no key bindings.
|
||
|
||
You can edit these lines to change the places where the new macro
|
||
is stored.
|
||
|
||
|
||
Format of keyboard macros during editing:
|
||
|
||
Text is divided into \"words\" separated by whitespace. Except for
|
||
the words described below, the characters of each word go directly
|
||
as characters of the macro. The whitespace that separates words
|
||
is ignored. Whitespace in the macro must be written explicitly,
|
||
as in \"foo SPC bar RET\".
|
||
|
||
* The special words RET, SPC, TAB, DEL, LFD, ESC, and NUL represent
|
||
special control characters. The words must be written in uppercase.
|
||
|
||
* A word in angle brackets, e.g., <return>, <down>, or <f1>, represents
|
||
a function key. (Note that in the standard configuration, the
|
||
function key <return> and the control key RET are synonymous.)
|
||
You can use angle brackets on the words RET, SPC, etc., but they
|
||
are not required there.
|
||
|
||
* Keys can be written by their ASCII code, using a backslash followed
|
||
by up to six octal digits. This is the only way to represent keys
|
||
with codes above \\377.
|
||
|
||
* One or more prefixes M- (meta), C- (control), S- (shift), A- (alt),
|
||
H- (hyper), and s- (super) may precede a character or key notation.
|
||
For function keys, the prefixes may go inside or outside of the
|
||
brackets: C-<down> = <C-down>. The prefixes may be written in
|
||
any order: M-C-x = C-M-x.
|
||
|
||
Prefixes are not allowed on multi-key words, e.g., C-abc, except
|
||
that the Meta prefix is allowed on a sequence of digits and optional
|
||
minus sign: M--123 = M-- M-1 M-2 M-3.
|
||
|
||
* The `^' notation for control characters also works: ^M = C-m.
|
||
|
||
* Double angle brackets enclose command names: <<next-line>> is
|
||
shorthand for M-x next-line RET.
|
||
|
||
* Finally, REM or ;; causes the rest of the line to be ignored as a
|
||
comment.
|
||
|
||
Any word may be prefixed by a multiplier in the form of a decimal
|
||
number and `*': 3*<right> = <right> <right> <right>, and
|
||
10*foo = foofoofoofoofoofoofoofoofoofoo.
|
||
|
||
Multiple text keys can normally be strung together to form a word,
|
||
but you may need to add whitespace if the word would look like one
|
||
of the above notations: `; ; ;' is a keyboard macro with three
|
||
semicolons, but `;;;' is a comment. Likewise, `\\ 1 2 3' is four
|
||
keys but `\\123' is a single key written in octal, and `< right >'
|
||
is seven keys but `<right>' is a single function key. When in
|
||
doubt, use whitespace."
