;;; Commentary:

;; The kmacro package provides the user interface to emacs' basic
;; keyboard macro functionality.  With kmacro, two function keys are
;; dedicated to keyboard macros, by default F3 and F4.

;; Note: The traditional bindings C-x (, C-x ), and C-x e are still
;; supported, but for some users these bindings are too hard to type
;; to be really useful for doing small repeated tasks.

;; To start defining a keyboard macro, use F3.  To end the macro,
;; use F4, and to call the macro also use F4.  This makes it very
;; easy to repeat a macro immediately after defining it.
;;
;; You can call the macro repeatedly by pressing F4 multiple times, or
;; you can give a numeric prefix argument specifying the number of
;; times to repeat the macro.  Macro execution automatically
;; terminates when point reaches the end of the buffer or if an error
;; is signaled by ringing the bell.

;; When you define a macro with F3/F4, it is automatically added to
;; the head of the "keyboard macro ring", and F4 actually executes the
;; first element of the macro ring.
;;
;; Note: an empty macro is never added to the macro ring.
;;
;; You can execute the second element on the macro ring with C-u F4 or
;; C-x C-k C-l, you can use C-x C-k C-p and C-x C-k C-n to cycle
;; through the macro ring, and you can swap the first and second
;; elements with C-x C-k C-t.  To delete the first element in the
;; macro ring, use C-x C-k C-d.
;;
;; You can also use C-x C-k C-s to start a macro, and C-x C-k C-k to
;; end it; then use C-k to execute it immediately, or C-x C-k C-k to
;; execute it later.
;;
;; In general, immediately after using C-x C-k followed by one of C-k,
;; C-l, C-p, or C-n, you can further cycle the macro ring using C-p or
;; C-n, execute the first or second macro using C-k or C-l, delete
;; the head macro with C-d, or edit the current macro with C-e without
;; repeating the C-x C-k prefix.

;; If you enter F3 while defining the macro, the numeric value of
;; `kmacro-counter' is inserted using the `kmacro-counter-format', and
;; `kmacro-counter' is incremented by 1 (or the numeric prefix value
;; of F3).
;;
;; The initial value of `kmacro-counter' is 0, or the numeric prefix
;; value given to F3 when starting the macro.
;;
;; Now, each time you call the macro using F4, the current
;; value of `kmacro-counter' is inserted and incremented, making it
;; easy to insert incremental numbers in the buffer.
;;
;; Example:
;;
;; The following sequence: M-5 F3 x M-2 F3 y F4 F4 F4 F4
;; inserts the following string:  x5yx7yx9yx11y

;; A macro can also be called using a mouse click, default S-mouse-3.
;; This calls the macro at the point where you click the mouse.

;; You can edit the last macro using C-x C-k C-e.

;; You can append to the last macro using C-u F3.

;; You can set the macro counter using C-x C-k C-c, add to it using C-x C-k C-a,
;; and you can set the macro counter format with C-x C-k C-f.

;; The following key bindings are performed:
;;
;;           Normal                         While defining macro
;;           ---------------------------    ------------------------------
;;  f3       Define macro                   Insert current counter value
;;           Prefix arg specifies initial   and increase counter by prefix
;;           counter value (default 0)      (default increment: 1)
;;
;;  C-u f3   APPENDs to last macro
;;
;;  f4       Call last macro                End macro
;;           Prefix arg specifies number
;;           of times to execute macro.
;;
;;  C-u f4   Swap last and head of macro ring.
;;
;;  S-mouse-3  Set point at click and       End macro and execute macro at
;;             execute last macro.          click.
