Images and Links

All decorative images on this site contain both ALT text and TITLE text. These tags are commonly used by browsers to render 'Alternative Text' for every decorative image; some browsers render these tags as tooltips. ALT and TITLE text may be picked up by the specialist screen-readers used by disabled users, and in many cases this text can be rendered audibly. Users with images switched off in their browsers will see this ALT text displayed as place holders where the images would normally appear within the webpage.

All hyperlinks on this website use the TITLE tag. This means that tooltips for links are displayed in commonly used browsers. Specialist browsers used by disabled users may also use these tags to aid accessibility.

Accesskeys

This website has adopted the UK Government Accesskeys System. This system provides keyboard shortcuts as a means of navigation and is intended primarily for users with limited physical capabilities.

The addition of accesskeys to this website is dependent on two factors:
  • The operating system in use by the user.
  • The browser being used. The accesskey attribute is not supported by every browser. Thankfully, however, accesskeys are supported in the majority of popular browsers such as Internet Explorer 4 and above, Netscape 6x and above and Mozilla.

Using the AccessKeys System
Use of the accesskey system is dependent on your operating system:
  • On Windows-based systems the user must press the 'Alt Key' and the relevant accesskey. On Internet Explorer this must be followed by the Return Key.
  • On Macintosh-based systems the user must press the 'Ctrl Key' and the relevant accesskey.

Listed below is the recommended UK Government Accesskeys Standard:
1 = Homepage (in use)
2 = What's New ? (in use)
3 = Sitemap (in use)
4 = Search (in use)
5 = Frequently Asked Questions
6 = Help (in use)
7 = Complaints Procedure
8 = Terms and Conditions (in use)
9 = Feedback Form (in use)
0 = Accesskey Details (in use)
S = Skip Navigation (in use)

Accesskeys in use on this website are marked as such in the above list.
