Just a thought...

I think that would be nice, but a scrolling mouse is allready like a
track ball in the vertical direction. I usually look through the pdf's
and then print the current view, than go over to the equipment.
Sometimes I tape sections together. I worked on much equipment from old
faxes, that it was a miracle I could do anything with it.
I sometimes convert autocad to pdf. same viewing result. I have not
tried converting clipboard to gif. and Jpeg, forget it.
