Today I learned how to record a macro on Doom Emacs and play it as many times as you want.

First, press q <letter> (or M-x evil-record-macro RET <letter>). This will start recording the macro at register <letter>.

Then, do everything you want to do, and when done, press q to quit recording mode.

To replay the macro you’ve just stored in the <letter> register, press @ <letter> (or M-x evil-execute-macro RET <letter>). Personally, when I don’t want to overthink about which register to use, I just hit q q and then Q, which replays the last stored macro.

If you want to repeat the macro `N` times though, you have to prepend the replay commands with the universal argument (prefix). Vanilla Emacs binds the prefix to C-u. Doom Emacs binds it to SPC u.

So, if you want to execute the last recorded macro twice, press SPC u 2 Q.
