-'''Keyboard macros''' can be used to automate or repeat tedious editing tasks in Emacs.
-==Basic Use==
-; {{Keys|F3}}, or {{Keys|C-x (}}
-: Start defining a macro.
-; {{Keys|F4}}, or {{Keys|C-x )}}
-: Stop defining a macro.
-; {{Keys|F4}}, or {{Keys|C-x e}}
-: Execute a macro
-; {{Keys|C-u 37 C-x e}} or {{Keys|C-u 37 F4}}
-: Execute a macro multiple times, using [[prefix argument]]
-; {{Keys|C-u 0 C-x e}}
-: Execute a macro until the end of the buffer
-==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,
-;; then enter the text in that file's own buffer.
-</pre>
-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.
-# 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.
-<ol start="5">
-<li>Hit <code>C-e C-f</code> to move point to the beginning of the next line.</li>
-<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">
-<li>Hit <code>C-x e</code> once to call that macro.</li>
-<li>Continue hitting <code>e</code> to call it several times. Hit any other key to get out of the macro repetition.</li>
-</ol>
-==Saving macros==
-{{Manual|emacs|Save-Keyboard-Macro|Save Keyboard Macro}}
-===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==
-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>
-Now execute the macro four times with the command <code>C-x e e e e</code> and you get:
-line number 1<br />
-line number 2<br />
-line number 3<br />
-line number 4
