Many Firefox keyboard combinations are the same as those of Internet Explorer. In particular, menu navigation uses the same combinations of arrow keys and Alt as most Windows applications, and navigation within text-editing fields supports the same keystrokes as most text editors (Ctrl+Left Arrow to move one word left, for example). Scrolling keys such as Page Up and Page Down work as you'd expect, too. The table below shows the major keys used by both browsers. (On the Macintosh, substitute Command for Ctrl and Option for Alt.)
