Actually Rokle you don't have to do three presses. If you press and hold the second time all other doors unlock and then if you continue to hold, after 5 secs or so the windows begin to move. Also any press and hold after the first one (second, third, fourth ... )will do the window thing as you have shown.
I think the
thing was just him agreeing with you? Although "duh" does imply a bit more.
