- Navigation shortcuts
There is a short menu at the start of every page that allows you to jump directly to the most important parts of the page, including main content and navigation. Sighted people who use the keyboard to navigate will see these links appear on screen when using the Tab key to navigate through the page. When keyboard-navigating, the element currently in focus has been highlighted.
Access keys have not been used to avoid conflicting with other keyboard shortcuts.
All pages follow a logical document structure. Screen reader users can get around pages quickly by moving between headings. Navigation menus are marked up as lists. Cascading Style Sheets (CSS) is used to control layout and presentation.
All pages have a tool enabling you to change the text size. You may also change the text size of this website to your preference through your browser:
- In Internet Explorer, select View, then Text
Size, and then your preferred size.
- In Firefox select View, then Zoom, and then
Zoom In or Zoom Out, or Ctrl/Cmd + Plus or Minus. (Enable the Zoom Text Only
option on that menu if you have a small screen.)
- In Safari select View, then Zoom In or Zoom
Out, or Ctrl/Cmd + Plus or Minus. (Enable the Zoom Text Only option on that
menu if you have a small screen.)

We strive to comply with the W3C WAI's Web Content Accessibility Guidelines and aim for our pages to conform to a minimum of WAI-A compliance. Wherever possible, level AA and AAA requirements are also met. See Caveats below.
