This site contains a number of keyboard shortcuts, called "accesskeys," to assist in navigating. Each Internet browser has a different method of accessing these keys:
Internet Explorer on a PC use ALT+Accesskey
Firefox on PC use ALT+SHIFT+Accesskey
Firefox and Safari on Apple or Linux use CTRL+Accesskey
Please note: Internet Explorer users may also need to hit the “enter” key to activate a link. Apple users with Spaces enabled may need to use the accesskey for Skip to the main navigation (A); then, TAB through the navigation and press "enter" to activate a link.
