Has anyone been able to make a scrollbar yet?

[Eloa]

I know the scrollbars themselves are really messy right now, but has anyone found out how to make 2 separate buttons that scroll?
I have the concept, just unable to execute it as of now. If we had string manipulation functions it'd be easy.
Have a subpage in a blank window thats the size of the window you wanna scroll, have a button to scroll down that takes the x and y from the subpage location and separate them into 2 'variables' and add some to the y and them put them back together and subpage.location=varx,newy.

Anyone?
