Auto scroller

Hi,thanks for helping me a lot in this forum.
Hope one day I can like you all helping others
solving problems!Coz Im not that good now.

Well,I have an idea about the scrollpane in Flash UI
components.I have a movieclip inside the scrollpane with
200 x 600 and the viewable screen is 200 x 200.
So I have a horizontal scroll. Can I make it like autoscroll?
let’s say I have a button, when i click on it, the scrollpane
will auto scroll from left to right and then back to left again
continuously. When I disable it (button) again, the scrollpane
will back to normal which user can drag the scrollbar again.

Another question: Can I make the scroll wheel at my mouse
to scroll the scrollpane horizontally in flash?

Thanks a lot guys!

add-on:
Just wanna let you know that Im not scrolling text but a movieclip.

Am I saying something impossible in flash here?
Hope someone can give me a hint. Thanx!
