Please note: While we aim to provide full accessibility in all new content on the website, some of our older pages may not yet meet all the standards outlined here.
The following features improve navigation for screen reader users, keyboard navigation and users of text-only browsers
At the start of every page is a short menu that allows you to jump directly to the most important parts of the page, including main content and navigation. Each of these also has an access key associated with it.
Sighted users who use the keyboard to navigate will see these links appear on screen when using the Tab key to navigate through the page.
Access keys are keyboard shortcuts that replace the need to use the mouse for navigation in browsers that support them. In Internet Explorer on Windows, you can press ALT + an access key; on Macintosh, you can press Control + an access key. Then press Enter to activate the link.
The following access keys are available thoughout the website:
S - Skip navigation
1 - Home page
3 - Site map
0 - Access key details
These access keys have been chosen to follow the UK Government website guidelines where applicable, in order to support the adoption of a useful standard. Wherever possible, they also avoid conflicting with commonly-used screen reader keyboard shortcuts.
