Certain menu

An effect that I like to use involves rolling over a movie object and motion occurs and when rolling off of this same object the opposite motion occurs. I use this code on the first frame:

stop();
this.useHandCursor = 0;
this.onEnterFrame = function() {
if (rewind == true) {
prevFrame();
}
};
this.onRollOver = function() {
rewind = false;
play();
};
this.onRollOut = function() {
rewind = true;
};

and then

stop();

on the last frame.

What I can’t do with this code is then have a button appear after the first motion. Much like this menu does - http://comedy.aol.com/viralvideos

This style of menu probably has a name, but I can’t think of it, so it was hard to do a search. Can someone please send me to a place that will give me some of the code for this type of menu.

Thanks in advance…
