M-/

I press this a lot. It's the built-in autocompletion key. It took me an amazingly long time to discover this. It doesn't require any setup, and it doesn't know anything about programming languages, but that doesn't really matter. It indexes all the tokens in all the currently open buffers, and tries to complete the current word you're typing when you press M-/ . If you don't like the completion, hit M-/ again for the next one, etc. Works for text too. bash also has autocompletion on this key."
