Ok, I'm going to ask something and risk sounding completely stupid. When using autocomplete, pressing a stop character fills in the rest of the keyword followed by the stop character. Isn't there a quick keypress that will fill in the selected word without any follow-up character? Yes, you can double-click with the mouse, but that's too slow and you'd be quicker just typing. The way I would have expected it to work is that you'd start typing the word, autocomplete shows some alternatives, you quickly cursor down and press enter to select the keyword you want. Am I missing something because as it stands, the autocomplete doesn't seem very useful at the moment?
