Access keys make navigating websites much easier, both for screen readers but also for people who find it quicker to use the keyboard to navigate around a website.
For example, Windows users can navigate with the Accesskey feature by typing ALT+Accesskey. On the Mac, you would use CTRL+Accesskey (not COMMAND+Accesskey, which can produce undesired effects). Internet Explorer users may also need to hit the "enter" key to activate a link.
Windows users will find that accesskeys take precedence over application commands, which can still be accessed from the keyboard by first typing the menu shortcut key (usually ALT) followed by the letter corresponding to the desired menu item.
This website also uses the tab key to make navigation easier. When you press the tab key, you go directly to the navigation links in page. This allows fast navigation without needing to use the mouse.
Note: The accesskey attribute is currently only supported by the following web browsers:
