29 ;; The `C-x C-k e' (`edit-kbd-macro') command edits a keyboard macro
30 ;; in a special buffer. It prompts you to type a key sequence,
31 ;; which should be one of:
33 ;; * RET or `C-x e' (call-last-kbd-macro), to edit the most
34 ;; recently defined keyboard macro.
36 ;; * `M-x' followed by a command name, to edit a named command
37 ;; whose definition is a keyboard macro.
39 ;; * `C-h l' (view-lossage), to edit the 300 most recent keystrokes
40 ;; and install them as the "current" macro.
42 ;; * any key sequence whose definition is a keyboard macro.
44 ;; This file includes a version of `insert-kbd-macro' that uses the
45 ;; more readable format defined by these routines.
47 ;; Also, the `read-kbd-macro' command parses the region as
48 ;; a keyboard macro, and installs it as the "current" macro.
49 ;; This and `format-kbd-macro' can also be called directly as
52 ;; Type `C-h m', or see the documentation for `edmacro-mode' below,
53 ;; for information about the format of written keyboard macros.
55 ;; `edit-kbd-macro' formats the macro with one command per line,
56 ;; including the command names as comments on the right. If the
57 ;; formatter gets confused about which keymap was used for the
58 ;; characters, the command-name comments will be wrong but that
59 ;; won't hurt anything.
61 ;; With a prefix argument, `edit-kbd-macro' will format the
62 ;; macro in a more concise way that omits the comments.

348 To abort the edit, just kill this buffer with \\[kill-buffer] RET.
350 Press \\[edmacro-insert-key] to insert the name of any key by typing the key.
352 The editing buffer contains a \"Command:\" line and any number of
353 \"Key:\" lines at the top. These are followed by a \"Macro:\" line
354 and the macro itself as spelled-out keystrokes: `C-x C-f foo RET'.
356 The \"Command:\" line specifies the command name to which the macro
357 is bound, or \"none\" for no command name. Write \"last-kbd-macro\"
358 to refer to the current keyboard macro (as used by \\[call-last-kbd-macro]).
360 The \"Key:\" lines specify key sequences to which the macro is bound,
361 or \"none\" for no key bindings.
363 You can edit these lines to change the places where the new macro
367 Format of keyboard macros during editing:
369 Text is divided into \"words\" separated by whitespace. Except for
370 the words described below, the characters of each word go directly
371 as characters of the macro. The whitespace that separates words
372 is ignored. Whitespace in the macro must be written explicitly,
373 as in \"foo SPC bar RET\".
375 * The special words RET, SPC, TAB, DEL, LFD, ESC, and NUL represent
376 special control characters. The words must be written in uppercase.
378 * A word in angle brackets, e.g., <return>, <down>, or <f1>, represents
379 a function key. (Note that in the standard configuration, the
380 function key <return> and the control key RET are synonymous.)
381 You can use angle brackets on the words RET, SPC, etc., but they
382 are not required there.
384 * Keys can be written by their ASCII code, using a backslash followed
385 by up to six octal digits. This is the only way to represent keys
386 with codes above \\377.
388 * One or more prefixes M- (meta), C- (control), S- (shift), A- (alt),
389 H- (hyper), and s- (super) may precede a character or key notation.
390 For function keys, the prefixes may go inside or outside of the
391 brackets: C-<down> = <C-down>. The prefixes may be written in
392 any order: M-C-x = C-M-x.
394 Prefixes are not allowed on multi-key words, e.g., C-abc, except
395 that the Meta prefix is allowed on a sequence of digits and optional
396 minus sign: M--123 = M-- M-1 M-2 M-3.
398 * The `^' notation for control characters also works: ^M = C-m.
400 * Double angle brackets enclose command names: <<next-line>> is
401 shorthand for M-x next-line RET.
403 * Finally, REM or ;; causes the rest of the line to be ignored as a
406 Any word may be prefixed by a multiplier in the form of a decimal
407 number and `*': 3*<right> = <right> <right> <right>, and
408 10*foo = foofoofoofoofoofoofoofoofoofoo.
410 Multiple text keys can normally be strung together to form a word,
411 but you may need to add whitespace if the word would look like one
412 of the above notations: `; ; ;' is a keyboard macro with three
413 semicolons, but `;;;' is a comment. Likewise, `\\ 1 2 3' is four
414 keys but `\\123' is a single key written in octal, and `< right >'
415 is seven keys but `<right>' is a single function key. When in
416 doubt, use whitespace."
