Rollover question [renamed]

i’m still pretty new to flash so i’m not sure how to do a rollover/mouse thing that i want to do.
i basically just need to know how to make something follow the mouse as you roll over it. i have a timeline and i want there to be a bar that “slides” as you move the mouse over the timeline. i guess pretty much like a scrollbar. then i want to be able to click on whatever year the bar is stopped on (which will then take me to a movie clip describing that year).
if there’s an easy to follow tutorial for this out there, let me know! otherwise, pleeeaaasse help!
thanks!!!
