@cindex keyboard macro
In this chapter we describe how a sequence of editing commands can
be recorded and repeated multiple times.
In this chapter we describe how to record a sequence of editing
commands so you can repeat it conveniently later.
A @dfn{keyboard macro} is a command defined by the user to stand for
another sequence of keys. For example, if you discover that you are
about to type @kbd{C-n C-d} forty times, you can speed your work by
defining a keyboard macro to do @kbd{C-n C-d} and calling it with a
repeat count of forty.
about to type @kbd{C-n M-d C-d} forty times, you can speed your work by
defining a keyboard macro to do @kbd{C-n M-d C-d}, and then executing
it 39 more times.
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.
