Access keys

Most browsers support jumping to specific links by typing keys defined on the site. On Windows, press ALT + an access key; on Macintosh, press Control + an access key.

We have defined the following access keys:

Home page
Contact Us
Jump to site navigation
Jump to content


Whenever possible, links are written to make sense when read out of context. Many browsers (such as JAWS, can extract the list of links on a page and allow the user to browse the list separately from the page.


All content images include descriptive ALT attributes. Purely decorative graphics include null ALT attributes.

Visual design

This website uses cascading style sheets for visual layout.

The stylesheet uses only relative font sizes, which are compatible with the user-specified “text size” option in visual browsers. For example, in Internet Explorer you can make your default text size larger under the View menu by selecting Text Size, Larger (or Largest).

If your browser or browsing device does not support stylesheets, the content of each page is still readable.
