Doom-emacs: [HOWTO] Make the leader key popup faster and timeout?

[dfischer]

What I want to achieve
When I press spc I want that popup to happen more quickly before waiting for another key. Is there a way to modify the timeout here?

Similarly if I don't type a sequence fast enough, I'd like the command to expire so I can retry more quickly.

(setq which-key-idle-delay 0.1)

Occasionally, which-key will not obey this on first load. In which case, just load it before setting it:

(require 'which-key)
(setq which-key-idle-delay 0.1)

Similarly if I don't type a sequence fast enough, I'd like the command to expire so I can retry more quickly.

This is an problem with base Emacs. There is no "timing out" when it comes to key sequences.

[dfischer]

@hlissner so the appropriate key combo afterwards is just press esc twice or so until it resets saying something like command not found?

[hlissner]

Yes. Either ESC or C-g. Since they are the "universal" abort keys in Emacs, they are rarely bound to, and are most likely to emit the command not found error (which we want).

Thank you very much. Appreciate the help.
