accessing main timeline

Hi this may be pretty simple (but because of my weak programming skills :) ) I'm struggling.

I'm using flash CS 5.5 and AS 3.0 . I've a movieclip that contains 3 more moviclips that are acting as toggle buttons. I want to change frame number / label of main time line upon click of these buttons. With _root no longer available I dont know know how to do it.

Many thanks

If I understood You right..
It has to do with MovieClip(parent).mc. and gotoAndStop event.target.name..

Worked like a charm .. many thanks :)
