==Example usage==
 +
Consider the standard <code>*scratch*</code> buffer:
 +
 
 +
<pre>
 +
;; This buffer is for notes you don't want to save, and for Lisp evaluation.
 +
;; If you want to create a file, visit that file with C-x C-f,

# Make sure [[point]] is at the start of the buffer.
 +
# Hit <code>C-x (</code> to start recording your macro. '''Note:''' If you hit <code>C-g</code> or if an error occurs, your keyboard macro recording will stop.
 +
# Hit <code>C-s</code> followed by <code>a</code> to find the first "a". Now, point is right after the first "a" in the text.
 +
# Hit backspace to delete that "a".
 +
 
 +
The first occurrence of "a" of the first line has been deleted. Let's move point to the beginning of the next line and then stop recording.

<li>Hit <code>C-x )</code> to finish the recording of our macro.</li>
 +
</ol>

The macro you have just recorded performs the operation of removing the first occurrence of "a" it can find and then moving point to the next line.
 +
 
 +
<ol start="7">

===Binding to a key===
 +
To bind a keyboard macro to a key use <code>C-x C-k b</code>.  To avoid problems caused by overriding existing bindings, the key sequences <code>C-x C-k 0</code> through <code>C-x C-k 9</code> and <code>C-x C-k A</code> through <code>C-x C-k Z</code> are reserved for your own keyboard macro bindings. You can, however, bind a keyboard macro to whatever you like.

Variables can be stored in lisp or in [[registers]]. Here's an example using lisp:

<pre>

[M-: (setq x 1)]
 +
<F3>
 +
Line number [C-u M-: x]
 +
[M-: (setq x (+ x 1))]
 +
<F4>
 +
</pre>
 +

Basic Keyboard Macro (`(info "(emacs) Basic Keyboard Macro")')

Keyboard macros can be used to automate or repeat tedious editing tasks in Emacs.


Basic Use

[F3], or [C-x (]
Start defining a macro.
[F4], or [C-x )]
Stop defining a macro.
[F4], or [C-x e]
Execute a macro
[C-u 37 C-x e] or [C-u 37 F4]
Execute a macro multiple times, using prefix argument
[C-u 0 C-x e]
Execute a macro until the end of the buffer

Example usage

Consider the standard *scratch* buffer:

;; This buffer is for notes you don't want to save, and for Lisp evaluation.
;; If you want to create a file, visit that file with C-x C-f,
;; then enter the text in that file's own buffer.

Suppose you want to remove the first occurrence of the letter "a" on every row in that piece of text. You could write a regular expression to do the job, but let's assume you want to use a keyboard macro this time.

  1. Make sure point is at the start of the buffer.
  2. Hit C-x ( to start recording your macro. Note: If you hit C-g or if an error occurs, your keyboard macro recording will stop.
  3. Hit C-s followed by a to find the first "a". Now, point is right after the first "a" in the text.
  4. Hit backspace to delete that "a".

The first occurrence of "a" of the first line has been deleted. Let's move point to the beginning of the next line and then stop recording.

  1. Hit C-e C-f to move point to the beginning of the next line.
  2. Hit C-x ) to finish the recording of our macro.

The macro you have just recorded performs the operation of removing the first occurrence of "a" it can find and then moving point to the next line.

  1. Hit C-x e once to call that macro.
  2. Continue hitting e to call it several times. Hit any other key to get out of the macro repetition.

Saving macros

Binding to a key

To bind a keyboard macro to a key use C-x C-k b. To avoid problems caused by overriding existing bindings, the key sequences C-x C-k 0 through C-x C-k 9 and C-x C-k A through C-x C-k Z are reserved for your own keyboard macro bindings. You can, however, bind a keyboard macro to whatever you like.

Variables

Variables can be stored in lisp or in registers. Here's an example using lisp:

[M-: (setq x 1)]
<F3>
Line number [C-u M-: x]
[M-: (setq x (+ x 1))]
<F4>

Now execute the macro four times with the command C-x e e e e and you get:

line number 1
line number 2
line number 3
line number 4
