We have attempted to make this site standards compliant and accessible to all browser and other user agent technologies. Undoubtedly we have failed someplace—perhaps badly. If you have trouble with this site, please write our Webmaster with details of your difficulty and any known fixes or reference material.
Most browsers support jumping to specific links by typing keys defined on the web site. In MSIE on Windows, you can press ALT + an access key and return; on Macintosh, you can press Control + an access key and return. Gecko-based browsers (Firefox, Netscape, Mozilla) and Safari do not require the return. Opera makes extensive use of keyboard shortcuts and so we quote their instructions on access keys:
Opera Access Keys
Some pages offer access key shortcuts. Pressing the designated key will activate the associated link or form input. Many sites that offer this feature will have an accessibility statement documenting the keys they use.
Access keys used by pages may conflict with Opera's own shortcuts, so to activate access keys in Opera, you will need to switch into access-key mode first. Press Shift+Esc to enter access-key mode. You can then press the appropriate access key to activate the link or form input. To exit access-key mode, press Shift+Esc again. Access-key mode will automatically exit as soon as you press an access key, or load another page.
For example; if a page offers the access key S to search the site, you could activate the search by pressing Shift+Esc then S.
All pages on this site define the following access keys:
1 - Home page
2 - Skip navigation
3 - Go to navigation
9 - Feedback
0 - Accessibility statement
