Is there a nextFrame equivalent to move from one frame to two frames on?

ummm basically what the title says… im not an actionscript specialist so i was wonderinf if this was possible - its my way of going around scripting lol. the reason i would like to know is coz the same movie clip will be used several times, but once a button inside this movie clip is clicked, i would like the playhead (on the root timeline) to move two frames forward.

Also, if im correct (if not, please tell me) nextFrame() goes to the next frame and stops? it deosn’t play on? is there an equivalent that moves to the next frame and plays on?

Thanks so much!
