Most web browsers (although not all the major ones) support linking to specific pages by typing named access keys.
Windows users: press Alt + an access key.
Macintosh users: press Control + an access key.
All pages on this site use the following access keys for common tasks:
In some browsers the access key may take you to the page's link rather than the page itself.
In this case press Enter when on the link.
The Skip Navigation access key goes straight to the page's main content, bypassing the navigation links. If there are any error or status messages it will position you at the begining of these.
This site does not use relative text sizing.
This means that in some browsers the font cannot be resized using the browser's text size facility.
If this causes you a problem we suggest you download an alternative browser that does not have this limitation.
For example Firefox,
which is available for Windows, Mac OS X and Linux i686.
