I have an unofficial patch that changes the Ctrl+MouseWheel action from zoom in/zoom out to pageup/pagedn.
ConTEXT does it that way so I'm used to it, plus I scroll the page a billion times more than I change the font size.
It's a text editor... I just set it to 9px Courier New and never need it to change, so I made use of the mousewheel for something I do do.
If anyone is interested, I'll tell you what to do but you're on your own to recompile it with the patch.
Haha I said do do.
