When I start entering a command and pause, this helpful window pops up at the bottom:

enter image description here

When I don't pause, it doesn't show up.

But sometimes, it takes more time to complete a command that I know, e.g. if it requires me to access modifier keys like shift or control.

In those cases, this window briefly flashes and disappears, often also freezing up the editor for about half a second or so.

How can I increase this pause time so I'm only shown the command completions if the pause is longer than, say 2 seconds?

What are you using for showing command completions? That looks a like which-key. If that's the case, I think you should modify which-key-idle-delay:

Delay (in seconds) for which-key buffer to popup. This
 variable should be set before activating which-key-mode.

A value of zero might lead to issues, so a non-zero value is
(see https://github.com/justbur/emacs-which-key/issues/134).

You may need to disable and re-enable which-key-mode to see the change take effect.

  • I haven't installed anything myself, it's whatever that comes with spacemacs. I'll verify if I indeed am using which-key. Commented Jan 27, 2020 at 16:29
