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.
