If you have a mouse with a scroll wheel on it, you can do some cool tricks…
Shift & Spin
Ever wonder what happens when you hold down the Shift key on a web page and spin the wheel on your wheel mouse? Explorer goes either back or forward, depending on which direction you spin.
Give it a try. Open up Explorer and follow a few links. Then, hold down your SHIFT key and spin that wheel.
CTRL & Spin
If you are in a web browser (Explorer or Netscape) or reading an email in Outlook Express, hold down your Ctrl key and spin the wheel. It makes the text larger or smaller depending on which way you spin. For Opera users, it magnifies both the images and the text.
Not only does this spinning technique save lots of time, but it has the added bonus of impressing the heck out of any novice computer users in the area during said spin.
