Emacs Tip #4: Repeat Last Command
Some times you’d want to quickly repeat an Emacs command several times and most of the time it won’t have a convenient keybinding you can use to do this. Enter C-x z (repeat) - it simply repeats the most recently executed command. And the best part? After you’ve pressed C-x z once you can continue repeating the last command simply by pressing z. Vi(m) users will probably note that this is quite similar to the . command there.
For instance - if you want to execute the er/expand-region command (part of the expand-region package) a few times you can do it like this:
1
2
3
4
5
M-x er/expand-region
C-x z
z
z
z
Neat, ah?
