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