If your mouse has a scroll wheel on it there are a couple of
neat tricks you can do while surfing using IE that you may not
be aware of.
1) Hold down the Shift key and spin the mouse wheel on a web
page and Explorer goes backward or forward through your current
browser session's history, depending on which direction you
spin the wheel.
2) Hold down the Ctrl key and spin the wheel and text on the
web page you're viewing will get larger or smaller, depending
on which way you spin the wheel. For Opera and IE 7 users, it magnifies
both the images and the text. This won't work on all sites.
Sites using CSS to control the font size are unaffected, at
least in IE.
