Rollover scroller

I tried this tutorial but it’s not really what I want: http://www.kirupa.com/developer/flash5/scrolltext.htm

I want to have the same up/down buttons but i want the text to scroll on rollover. And I dont want to use the setvariable to input the text, i want to use a mask instead so i can scroll objects and such.

anyone know of a good tutorial for this? or can you post instructions here?
