Emacs: Repeat Last Command

Repeat Last Command

Alt+x repeat 【Ctrl+x z】

repeat the last command.

Once you called repeat, you can call it again by pressing or holding down the last key used for invoking repeat.

That means, for any command that does not have a shortcut (or if the shortcut is difficult to press), now you can repeat it by simply holding down a key.

For example, try Alt+x forward-word, now Ctrl+x z z z. It'll do it 3 times.

This is especially useful to repeat call-last-kbd-macro [see Emacs: Keyboard Macro] .

Major mode commands usually have keys such as Ctrl+c Ctrl+key that is hard to repeat. So the repeat command is super useful.

Repeat Last Complex Command

Alt+x repeat-complex-command 【Ctrl+x Alt+:】

Repeat the last command that has prompts.

Tip: repeat-complex-command is great for:

• Repeating a command without answering the prompts again.
• Get the actual emacs lisp code. Copy paste it elsewhere, edit and eval.
• Converting emacs Regular Expression from interactive form to lisp string form with all proper backslash escape added. [see Emacs Lisp: Convert Regex to Lisp Regex String]

List Command History

Alt+x list-command-history

list all recent commands called involving the Minibuffer.
