Keyboard Macros
===============

   A "keyboard macro" is a command defined by the user to abbreviate a
sequence of keys.  For example, if you discover that you are about to
type `C-n C-d' forty times, you can speed your work by defining a
keyboard macro to invoke `C-n C-d' and calling it with a repeat count
of forty.

`C-x ('
     Start defining a keyboard macro (`start-kbd-macro').

`C-x )'
     End the definition of a keyboard macro (`end-kbd-macro').

`C-x e'
     Execute the most recent keyboard macro (`call-last-kbd-macro').

`C-u C-x ('
     Re-execute last keyboard macro, then add more keys to its
     definition.

`C-x q'
     When this point is reached during macro execution, ask for
     confirmation (`kbd-macro-query').

`M-x name-last-kbd-macro'
     Give a command name (for the duration of the session) to the most
     recently defined keyboard macro.

`M-x insert-kbd-macro'
     Insert in the buffer a keyboard macro's definition, as Lisp code.

   Keyboard macros differ from other Emacs commands in that they are
written in the Emacs command language rather than in Lisp.  This makes
it easier for the novice to write them and makes them more convenient as
temporary hacks.  However, the Emacs command language is not powerful
enough as a programming language to be useful for writing anything
general or complex.  For such things, Lisp must be used.

   You define a keyboard macro by executing the commands which are its
definition.  Put differently, as you are defining a keyboard macro, the
definition is being executed for the first time.  This way, you see
what the effects of your commands are, and don't have to figure them
out in your head.  When you are finished, the keyboard macro is defined
and also has been executed once.  You can then execute the same set of
commands again by invoking the macro.
