Keyboard shortcuts

Access keys have been set up to allow a quick route to certain pages and sections of the website, without the need for a mouse. To activate these, hold down the ‘Alt’ key (for Windows), or ‘Ctrl’ key (for Apple Mac) and press one of the following keys. Visitors with an Internet Explorer browser will need to press ‘Enter’ afterwards:

C – Jump to main site navigation
M – Navigate to menu
T – Jump to top of page


The website has been designed to appear best on a monitor set at a screen resolution of 1280×1024 pixels and above although all major content sections fit on a 1024×768 pixel display.

Fonts, text sizes and colour are set with the use of Cascading Style Sheets (CSS) and can be overridden with your own preferred style sheet. Current methods for making these changes can be found in your browser help file.

It is also possible to increase or decrease the size of the text appearing on the site. This can be achieved by holding down the ‘Ctrl’ key (for Windows), or ‘Cmd’ key (for Apple Mac), then pressing + or – to alter the font size up or down respectively.
