Change text size easily when reading a page

Ever want to change the text size on a wikipedia page but can't be bothered to go to the browser menu?

If you have a wheel mouse and you hold down the "Ctrl" button whilst using the wheel on the mouse - you can make the text larger and smaller in an instant. Sometimes handy for template text or those References sections that have been made smaller than normal text.

As a bonus, this tip works in lots of other applications! (Generally used for zooming on Windows.)
