Fastforward and fast backward Buttons

Here's a method of creating a fast-forward and fast-backward buttons, if you hold down the back button, it'll speed backwards, and the same happens with the forward button, or you can just click a toggle button to just keep going faster. It's very simple, all I used is two extra MCs, in each one there's a delay for a 100 frames (assuming the fla was at 100bpm) before it starts rewinding backwards or fast forwarding.

You can shorten or expand the number of frames to make the delay shorter or longer, and make it rewind or forward faster or slower. The same method can also be used to play a timeline backwards instead of copying and reversing the frames, just create a movie and make it work like forwardRep or rewindRep, with only frames as 100-103 on the timeline.
