A lot of newer mice have a scroll wheel that “tilts” right and left when pushed, but until recently I never saw much use for this feature. As my eyes get older I find myself always using the Internet Explorer “magnify” feature located at the bottom right of the page. To use this feature usually requires a few clicks and scrolls to set and reset.
Using the mouse control applet I have set the tilt left and tilt right to correspond to keystrokes Ctrl+ and Ctrl- which yields instant magnification up and down in increments of 10% whe the tilt putton is nudged right or left with no trip to the bottom right and selecting a magnification level.
I’m pretty sure the applet software with almost any late model mouse with tilt right-left functions will allow you to do this. I have theLogitech Nano 450.
