How can i do that tranistion?

hi,i am new in actionscript and i need your help i wanna do that effect of reverse the actual scene then play button scene (scene = mc) for example:

i have a mc calles scenes that contains all animations of the buttom links

the home buttom is 1-50 frames of scene mc
the services button is 51-100 frames of scene mc
the about button goes to 101-150 frames of scene mc
the contact button goes to 151-200 frames of scene mc

ok what i wanna do is for example if home is playing then i pressed services button it reverse the actual escene(in this case home) and reverse it then when it is on the first frame of the home animation goes to the first frame animation of services in other words i want that he button first reverse the actual escene animation then play the animation button like this site http://www.itcatmedia.com/school look the transition between courses -faq - about us , first reverse the acutal scene the play the animation of the link you press i wanna do that,but i don“t know how please tell me if you can tell me in a very detail way i will appreciate.
