- ;;; 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
- ;; Emacs 19.18.) This package does not work with Emacs 18 or
- ;; Lucid Emacs.

-
- 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."
