Comment 2 for bug 1396944

Hi everyone, tab completion is already available. You just need to click one time on the terminal widget to trigger it. I understand that it's a little bit difficult to discover (we are probably going to have a small tutorial/presentation when the terminal is firstly launched), but is probably one of the fastest gestures. I personally don't like moving it to a left swipe: it's probably slower and we can't assign a "opposite" swipe right.
