Can I view a text only version?

The text-only button at the top of the screen provides you with fast loading pages with text rendered in a high contrast format. This feature also removes formatting as well as any images. 

Need help reading our website?

Our site conforms to web standards for accessibility and is compatible with most standard assistive software, including screen readers.

Do I have to use a mouse to navigate the website?

No. Use your arrow keys to scroll up or down the page. You can use your Tab key to move between links, and press Return or Enter to select one. To go back to the previous page, use the Backspace key.

We don't use access keys. Research suggests that these can sometimes conflict with shortcut keys used by assistive technologies.
