I use nvim. If I need to look something up, I use Telescope, which pops a modal up in the current buffer. Type the first few characters of whatever you’re looking for, and get a preview of it in the codebase, as well as the path. If I want to, I can then open that file for further investigation.

I personally don’t like the surprise of autocomplete, or of anything popping up on-screen that I didn’t ask for.
