That's a negative experience for me. If I'm pausing, it's because I need to think about something.
In that instant, a suggestion distracts me.
The chances of the suggestion being relevant to my pause are pretty low.
The best option is when you can invoke the autocomplete/docs on demand - using a convenient shortcut.
