Scrolling with mouse pointer

[Thierry]

I want to be able to scroll (move) to the bottom of the page simply by hovering the mouse near the bottom.

As the page in question can be very large, if you hover near the edge of the screen, the page should scroll to that direction.

So if you are putting the mouse near the right edge of the screen, the page would scroll to the right, you hover left it goes left etc.

 

Currently I've been trying it by having an <input image> following the mouse and constantly focusing on it when it nears the screen but its buggy and doesn't really work well.

 

Any ideas that could do it better?
