Access keys

  • Accesskey "0" = Accessibility
  • Accesskey "1" = Homepage
  • Accesskey "2" = Site Map
  • Accesskey "3" = Search
  • Accesskey "9" = Contact us
  • Accesskey "[" = Skip to content

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.

Is the type too small?

If you are using Microsoft Internet Explorer, go to the View menu at the top of your screen, select Text size, then choose to view with larger or smaller type. For other browsers, consult the browser Help for details on how to resize the text.
