Access keys

Access keys were designed to provide web site visitors with keyboard shortcuts to common pages of a web site. this is ideal, in theory, for visitors who cannot use a mouse, or to make navigating a web site for visitors with sight related issues.

We do not implement access keys because they can cause visitors to our web site more problems than they resolve:

The Royal National Institute for the Blind (RNIB), pioneers of accessibility in web sites, actually state that a "well ordered site with good structural mark up, clear link text and page titles, making good use of hidden navigation can do more for the user in terms of easing navigation than access keys can".


Most inks contain TITLE attributes that describe the purpose of the link in greater detail than is possible in the link text on the web page.

Where the link text fully describes the link we may have omitted a title attribute.


All content images on this web site include descriptive ALT and TITLE attributes so that screen readers will read the text to the web site visitor and text-only browsers will display the text in place of the image.

Images used in the construction of the web site will not include ALT and TITLE attributes as they graphics are not related to the content of the web page.

Visual design

The web site uses CSS (cascading style sheets) to format the visual layout and text content contained within it. The size of all text can be increased and decreased by the visitor's browser text-size settings.

If your browser does not support stylesheets, or text size manipulation, textual content can still be read.

Tables and forms

All input fields in forms on this web site are marked up with label tags. This enables visitors who find it difficult to use a mouse can click on the text beside the field to place the cursor inside the field.

All tables contain a summary so that screen readers can read a description of the table to their users.
