Forward & backward movment control in movie clips?

I have a movie clip of a 3d fly through of a map of my local town exported to Flash from Cinema 4D. What I want to is have control over going forward and backward through the movie clip to specific points upon hitting specific buttons. I don’t want to jump from point to point, I want to play and rewind from point to point.

Usual searches have come up with nothing. Where do I start?

Many thanks

Chris
