Making sections directly linkable in flash

hey gang,
I had my hands on an example of how to make a flash site directly linkable - as in after you clicked on certain sections, it would change the url to something specific, that would be able to refer to that particular section of the flash movie, not just restart at the beginning of the timeline.

I misplaced that tutorial, and I’ve been trying to look for such a thing all day.

any help is greatly appreciated.
