Call the last keyboard macro that you defined with C-x (.
A prefix argument serves as a repeat count. Zero means repeat until error.
When you call the macro, you can call the macro again by repeating
just the last key in the key sequence that you used to call this
command. See `kmacro-call-repeat-key' and `kmacro-call-repeat-with-arg'
for details on how to adjust or disable this behavior.
To make a macro permanent so you can call it even after defining
others, use M-x kmacro-name-last-macro.
