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 do `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 ordinary 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
intelligent or general.  For such things, Lisp must be used.

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