Help on scroll/list menu

Hey everyone , hope you can help me , but iam trying to figure out how to make the scroll/list menu in 2advanced’s portfolio section, it can be found here http://www.2advanced.com/flashindex.htm

I kinda had a idea on how to make it , by using a mask and movie clip which holds the buttons, and then just use the up and down buttons to move the movie clip up and down, but dnt really know how to really do this. Any help will be much appreciated, thanx

any help?

i basically want to know how to move a Movie clip up and down when a up or down button is pressed with restriction to how much i can move it up and down,

or if you know any other way this menu is done plz tell me
