Auto Scroll Cab?

[rcelegans]

Hello,
Does anyone know of an application that lets you scroll through the page automatically by pressing a button once, i.e auto-scroll? For example those of you who have used the isilo program or certain e-book readers know that you can just have the page scroll for you automatically with pause, and speed up/down functions. But I would like an application like this that works on any page that has scroll bars.

Your help is gratefully appreciated!
