How to access the frames of an entire animation within one keyframe

I’ve created a movie clip and within that movie clip I’ve posted my animation, thus making an animation within one keyframe (this makes it easier to manage because instead of having to say “gotoAndPlay(70)” I can put “gotoAndPlay(1)” for the standing animation, “gotoAndPlay(2)” for the moving animation, etc.) But I don’t know how to refer to the certain frames within that one keyframe via AS3.

Does anybody know how to do this? Been searching for a long time and haven’t seen anyone ask about this.

Also, if this is confusing, just give the word and I’ll give a better explanation.
