A new Vista trick I learned

The Off Campus blog brought to my attention the coolest Vista trick I've learned yet - resizing screens on the fly. Up till now, I thought my only choices were (1) changing the screen resolution, (2) messing with IE's View settings for web pages, (3) Windows's Magnifier. All of those are just a bit too much trouble for occasional instances of too-fine print. And now I found out that all I need is the control key and my mouse wheel - too cool!
