Ever wanted to zoom in and out (make text on a web page bigger or smaller) easily? At least on Windows, if you have a wheel mouse, hold down the [CTRL] key and move the mouse wheel. Wheee! I do this all the time, and maybe everyone knows about it. Just thought maybe there were those who didn't. Especially on a laptop with a small screen, or if you have bad or strained eyesight, it can be nice to zoom in a couple of clicks to make everything a tad easier to read.
