We have designed this website to be accessible as possible.
The tab key with the help of the enter, left, right, up and down arrows keys, can be used to access most things on a web page.
Tabbing runs through three areas of the screen in sequence. The top address bar and the favourites/history bars (if they are open) first, then any input forms and finally page links. To tab backwards press and hold the Shift key whilst tabbing.
The tab key is often marked with two arrows pointing horizontally in opposite directions. Usually the third key down on the extreme left hand side of the keyboard.
For those users that are partially sighted or have trouble reading the text, you can enlarge it by holding down Ctrl and pressing the + key on your keyboard. If you are a Mac user, hold down command key and +.
All images on this site are accompanied by a brief alternative text which where appropriate identifies an image or its function. This alternative text (alt-text) is generally only visible when the browser's automatic image loading feature is turned off.
All text links are written so that they make sense when read out of context.
