Using the site without a mouse

The window is split into three sections (frames):

1) Top navigation - to access general pages

2) Left navigation - to access the main content

3) The main content

You may jump clockwise between these sections and the address bar using Control + Tab (+Shift to reverse) and navigate within frames using Tab (+Shift ). Then use Enter to affect the function.

When any page is accessed, the keyboard focus is automatically shifted to the main content (in supporting browsers) so that the vertical scrollbar may be moved straight away with the up and down arrows.

Tabbing within the page allows access to links as well as the glossary pop up definitions.
It is recommended that you use the 'Next' arrows at the bottom of each page to go through the site.

Other examples - when a page is first opened:

Control + Tab three times takes you to the top menu to access the site information pages.

Control + Shift + Tab twice, takes you to the top of the left navigation menu. Tab through it and use Enter to go to a page.

Use Shift + Tab twice to get to the text size options below the left menu (or the 'Return' link, which may at times appear in place of the text panel). Continue with Shift + Tab to go up through the left navigation menu from the bottom.

A no frames/no javascript version of the site will be available shortly.
Otherwise the site adheres as much as possible to the W3C Web Accessibility Initiative: Level Double A.
