If you're having difficulty reading the text on a web page, you can magnify it in Firefox, Internet Explorer or Safari by pressing Ctrl-+ or ⌘-+ on a Mac. Other keys let you reduce the level of magnification (including making the page smaller than it started) or reset the magnification back to the default:

Increase Magnification:	Ctrl-+
Decrease Magnification:	Ctrl--
Reset to Default size:	Ctrl-0
