When Flash enters frame 3 of the controller movie clip (when it’s told to by our back button, which we’ll do later), we’re going to have it check to see what frame the menu movie clip is on in its timeline. If it’s on any frame greater than frame one, we’re going to tell it to rewind the menu by one frame, then go back to frame 2 of the controller clip’s timeline and do it all over again. That way it will continue rewinding one frame after another, over and over again, for as long as the loop continues - creating a smooth simulation of a rewind rather than a click-for-click jump one frame at a time.
When or if the menu movie clip is on frame 1 of its timeline, then the controller movie clip will jump to its first frame, where we inserted the stop – which will break the loop and place it on hold so that the playback pauses.
