Additional functionality to the scroll wheel

[dluby]

As an addition to use the scroll wheel to zoom in and out of a captured image, could you use the wheel click event switch to AutoFit and the double click event to switch to 100%?  Or is something like this already covered elsewhere?

interesting idea.. as i find using the middle mouse button very uncomfortable i never make it do anything in my apps.
is there a standard function for middle mouse button in drawing programs?

Sorry Mouser but I can't answer your question as I have no experience with drawing programs.  I do know clicking the wheel will close tabs in many applications.
