MovieClipButtons

Looking for tuts and info on movieClipButtons. I need to create a movie clip button that has a state showing that it has been pressed, so that user knows which links he has already visited. Possibly I would also like another state that plays an animation of the button the first time it appears (not first time it is pressed) meaning that the animation plays when the page builds up. Thats just minor though.

ThanksInAdvance
