How to use access keys on this website

We aim to make our website accessible to as many people as possible and are implementing the UK Government access keys system.

Access keys are keyboard shortcuts which allow a user to navigate a web site without using a mouse or other pointing device. This can sometimes be quicker and may assist those with motor skill difficulties.

In Internet Explorer 5+:
'alt + the access key' brings focus to the element. If a link, 'enter' will take the user to the linked destination.

In Mozilla Firefox:
'alt + shift + the access key' will take the user to the linked destination.

If using an Apple Mac:
Substitute the 'Ctrl' key for the 'Alt key'.
