Add timeout support

[introom]

Is it possible to add timeout support so that when which-key display is idle for 3 second, it is automatically cancelled?

Yes, it's possible, but why would you want to remain idle in the middle of a key sequence? Or is this is another situation?

[introom]

Some special case though, such as tmux sending keys (C-l) to all panes to clear the pane. And it happened that emacs is running in some pane. We want to cancel the C-l.

But a which-key timeout won't cancel the key sequence. which-key is passive. It doesn't manipulate the key sequences
