|
|
|
38 ;; The `C-x C-k' (`edit-kbd-macro') command edits a keyboard macro
|
|
|
39 ;; in a special buffer. It prompts you to type a key sequence,
|
|
|
40 ;; which should be one of:
|
|
|
41 ;;
|
|
|
42 ;; * RET or `C-x e' (call-last-kbd-macro), to edit the most
|
|
|
43 ;; recently defined keyboard macro.
|
|
|
44 ;;
|
|
|
45 ;; * `M-x' followed by a command name, to edit a named command
|
|
|
46 ;; whose definition is a keyboard macro.
|
|
|
47 ;;
|
|
|
48 ;; * `C-h l' (view-lossage), to edit the 100 most recent keystrokes
|
|
|
49 ;; and install them as the "current" macro.
|
|
|
50 ;;
|
|
|
51 ;; * any key sequence whose definition is a keyboard macro.
|
|
|
52 ;;
|
|
|
53 ;; This file includes a version of `insert-kbd-macro' that uses the
|
|
|
54 ;; more readable format defined by these routines.
|
|
|
55 ;;
|
|
|
56 ;; Also, the `read-kbd-macro' command parses the region as
|
|
|
57 ;; a keyboard macro, and installs it as the "current" macro.
|
|
|
58 ;; This and `format-kbd-macro' can also be called directly as
|
|
|
59 ;; Lisp functions.
|
|
|
60
|
|
136
|
61 ;; The `kbd' macro is a shorter-named and more efficient form of
|
|
|
62 ;; `read-kbd-macro'. Unlike `read-kbd-macro', it is evaluated at
|
|
|
63 ;; read-time, and doesn't bring any overhead to compiled programs. It
|
|
|
64 ;; is recommended to use in your programs and initializations, as you
|
|
|
65 ;; needn't know the internal keysym representation. For example:
|
|
118
|
66 ;;
|
|
|
67 ;; (define-key foo-mode-map (kbd "C-c <up>") 'foo-up)
|
|
134
|
68 ;;
|
|
136
|
69 ;; is the exact equivalent of
|
|
134
|
70 ;;
|
|
118
|
71 ;; (define-key foo-mode-map [(control ?c) up] 'foo-up)
|
|
134
|
72 ;;
|
|
118
|
73
|
|
22
|
74 ;; Type `C-h m', or see the documentation for `edmacro-mode' below,
|
|
|
75 ;; for information about the format of written keyboard macros.
|
|
|
76
|
|
|
77 ;; `edit-kbd-macro' formats the macro with one command per line,
|
|
|
78 ;; including the command names as comments on the right. If the
|
|
|
79 ;; formatter gets confused about which keymap was used for the
|
|
|
80 ;; characters, the command-name comments will be wrong but that
|
|
|
81 ;; won't hurt anything.
|
|
|
82
|
|
|
83 ;; With a prefix argument, `edit-kbd-macro' will format the
|
|
|
84 ;; macro in a more concise way that omits the comments.
|
|
|
85
|
|
|
86 ;; This package requires GNU Emacs 19 or later, and daveg's CL

358 and the macro itself as spelled-out keystrokes: `C-x C-f foo RET'.
|
|
|
359
|
|
|
360 The \"Command:\" line specifies the command name to which the macro
|
|
|
361 is bound, or \"none\" for no command name. Write \"last-kbd-macro\"
|
|
|
362 to refer to the current keyboard macro (as used by \\[call-last-kbd-macro]).
|

|
363

370
|
|
|
371 Format of keyboard macros during editing:
|
|
|
372
|
|
|
373 Text is divided into \"words\" separated by whitespace. Except for
|
|
|
374 the words described below, the characters of each word go directly
|
|
|
375 as characters of the macro. The whitespace that separates words
|
|
|
376 is ignored. Whitespace in the macro must be written explicitly,
|
|
|
377 as in \"foo SPC bar RET\".
|
|
|
378
|
|
136
|
379 * The special words RET, SPC, TAB, DEL, BS, LFD, ESC, and NUL represent
|
|
22
|
380 special control characters. The words must be written in uppercase.
|
|
|
381
|
|
|
382 * A word in angle brackets, e.g., <return>, <down>, or <f1>, represents
|
|
|
383 a function key. (Note that in the standard configuration, the
|
|
|
384 function key <return> and the control key RET are synonymous.)
|
|
|
385 You can use angle brackets on the words RET, SPC, etc., but they
|
|
|
386 are not required there.
|
|
|
387
|
|
|
388 * Keys can be written by their ASCII code, using a backslash followed
|
|
|
389 by up to six octal digits. This is the only way to represent keys
|
|
|
390 with codes above \\377.
|
|
|
391
|
|
|
392 * One or more prefixes M- (meta), C- (control), S- (shift), A- (alt),
|
|
|
393 H- (hyper), and s- (super) may precede a character or key notation.
|
|
|
394 For function keys, the prefixes may go inside or outside of the
|
|
|
395 brackets: C-<down> = <C-down>. The prefixes may be written in
|
|
|
396 any order: M-C-x = C-M-x.
|
|
|
397
|
|
|
398 Prefixes are not allowed on multi-key words, e.g., C-abc, except
|
|
|
399 that the Meta prefix is allowed on a sequence of digits and optional
|
|
|
400 minus sign: M--123 = M-- M-1 M-2 M-3.
|
|
|
401
|
|
|
402 * The `^' notation for control characters also works: ^M = C-m.
|
|
|
403
|
|
|
404 * Double angle brackets enclose command names: <<next-line>> is
|
|
|
405 shorthand for M-x next-line RET.
|
|
|
406
|
|
|
407 * Finally, REM or ;; causes the rest of the line to be ignored as a
|
|
|
408 comment.
|
|
|
409
|
|
|
410 Any word may be prefixed by a multiplier in the form of a decimal
|
|
|
411 number and `*': 3*<right> = <right> <right> <right>, and
|
|
|
412 10*foo = foofoofoofoofoofoofoofoofoofoo.
|
|
|
413
|
|
|
414 Multiple text keys can normally be strung together to form a word,
|
|
|
415 but you may need to add whitespace if the word would look like one
|
|
|
416 of the above notations: `; ; ;' is a keyboard macro with three
|
|
|
417 semicolons, but `;;;' is a comment. Likewise, `\\ 1 2 3' is four
|
|
|
418 keys but `\\123' is a single key written in octal, and `< right >'
|
|
|
419 is seven keys but `<right>' is a single function key. When in
|
|
|
420 doubt, use whitespace."
