29 | ;;; Usage: |
30 | ;; | |
31 | ;; The `C-x C-k' (`edit-kbd-macro') command edits a keyboard macro | |
32 | ;; in a special buffer. It prompts you to type a key sequence, | |
33 | ;; which should be one of: | |
34 | ;; | |
35 | ;; * RET or `C-x e' (call-last-kbd-macro), to edit the most | |
36 | ;; recently defined keyboard macro. | |
37 | ;; | |
38 | ;; * `M-x' followed by a command name, to edit a named command | |
39 | ;; whose definition is a keyboard macro. | |
40 | ;; | |
41 | ;; * `C-h l' (view-lossage), to edit the 100 most recent keystrokes | |
42 | ;; and install them as the "current" macro. | |
43 | ;; | |
44 | ;; * any key sequence whose definition is a keyboard macro. | |
45 | ;; | |
46 | ;; This file includes a version of `insert-kbd-macro' that uses the | |
47 | ;; more readable format defined by these routines. | |
48 | ;; | |
49 | ;; Also, the `read-kbd-macro' command parses the region as | |
50 | ;; a keyboard macro, and installs it as the "current" macro. | |
51 | ;; This and `format-kbd-macro' can also be called directly as | |
52 | ;; Lisp functions. | |
53 | ||
54 | ;; Type `C-h m', or see the documentation for `edmacro-mode' below, | |
55 | ;; for information about the format of written keyboard macros. | |
56 | ||
57 | ;; `edit-kbd-macro' formats the macro with one command per line, | |
58 | ;; including the command names as comments on the right. If the | |
59 | ;; formatter gets confused about which keymap was used for the | |
60 | ;; characters, the command-name comments will be wrong but that | |
61 | ;; won't hurt anything. | |
62 | ||
63 | ;; With a prefix argument, `edit-kbd-macro' will format the | |
64 | ;; macro in a more concise way that omits the comments. | |
65 | ||
66 | ;; This package requires GNU Emacs 19 or later, and daveg's CL | |
67 | ;; package 2.02 or later. (CL 2.02 comes standard starting with | |
68 | ;; Emacs 19.18.) This package does not work with Emacs 18 or | |
69 | ;; Lucid Emacs. | |

319 | and the macro itself as spelled-out keystrokes: `C-x C-f foo RET'. | |
320 | ||
321 | The \"Command:\" line specifies the command name to which the macro | |
322 | is bound, or \"none\" for no command name. Write \"last-kbd-macro\" | |
323 | to refer to the current keyboard macro (as used by \\[call-last-kbd-macro]). | |
324 | ||
325 | The \"Key:\" lines specify key sequences to which the macro is bound, | |
326 | or \"none\" for no key bindings. | |
327 | ||
328 | You can edit these lines to change the places where the new macro | |
329 | is stored. | |
330 | ||
331 | ||
332 | Format of keyboard macros during editing: | |
333 | ||
334 | Text is divided into \"words\" separated by whitespace. Except for | |
335 | the words described below, the characters of each word go directly | |
336 | as characters of the macro. The whitespace that separates words | |
337 | is ignored. Whitespace in the macro must be written explicitly, | |
338 | as in \"foo SPC bar RET\". | |
339 | ||
340 | * The special words RET, SPC, TAB, DEL, LFD, ESC, and NUL represent | |
341 | special control characters. The words must be written in uppercase. | |
342 | ||
343 | * A word in angle brackets, e.g., <return>, <down>, or <f1>, represents | |
344 | a function key. (Note that in the standard configuration, the | |
345 | function key <return> and the control key RET are synonymous.) | |
346 | You can use angle brackets on the words RET, SPC, etc., but they | |
347 | are not required there. | |
348 | ||
349 | * Keys can be written by their ASCII code, using a backslash followed | |
350 | by up to six octal digits. This is the only way to represent keys | |
351 | with codes above \\377. | |
352 | ||
353 | * One or more prefixes M- (meta), C- (control), S- (shift), A- (alt), | |
354 | H- (hyper), and s- (super) may precede a character or key notation. | |
355 | For function keys, the prefixes may go inside or outside of the | |
356 | brackets: C-<down> = <C-down>. The prefixes may be written in | |
357 | any order: M-C-x = C-M-x. | |
358 | ||
359 | Prefixes are not allowed on multi-key words, e.g., C-abc, except | |
360 | that the Meta prefix is allowed on a sequence of digits and optional | |
361 | minus sign: M--123 = M-- M-1 M-2 M-3. | |
362 | ||
363 | * The `^' notation for control characters also works: ^M = C-m. | |
364 | ||
365 | * Double angle brackets enclose command names: <<next-line>> is | |
366 | shorthand for M-x next-line RET. | |
367 | ||
368 | * Finally, REM or ;; causes the rest of the line to be ignored as a | |
369 | comment. | |
370 | ||
371 | Any word may be prefixed by a multiplier in the form of a decimal | |
372 | number and `*': 3*<right> = <right> <right> <right>, and | |
373 | 10*foo = foofoofoofoofoofoofoofoofoofoo. | |
374 | ||
375 | Multiple text keys can normally be strung together to form a word, | |
376 | but you may need to add whitespace if the word would look like one | |
377 | of the above notations: `; ; ;' is a keyboard macro with three | |
378 | semicolons, but `;;;' is a comment. Likewise, `\\ 1 2 3' is four | |
379 | keys but `\\123' is a single key written in octal, and `< right >' | |
380 | is seven keys but `<right>' is a single function key. When in | |
381 | doubt, use whitespace." | |
