Access Keys

Most browsers support jumping to specific links by typing keys defined on the Web site. Macintosh, press Control + an access key. On Windows, press ALT + an access key; this works for the Chrome browser. The Internet Explorer requires press ALT + an access key + Enter. Firefox requires SHIFT + ALT + an access key. recognizes the following access keys:

  • Access key 1 — Home page
  • Access key 4 — Search box
  • Access key 9 — Feedback (contact form)
  • Access key 0 — Accessibility statement

Navigation Aids

  • All pages have rel=home, search, glossary, and index links to aid navigation in text-only browsers and screen readers. Mozilla users can also take advantage of this feature by selecting the View menu, Show/Hide, Site Navigation Bar, Show Only As Needed (or Show Always). Opera 7 has similar functionality.
  • The home page and all subsequent pages include a search box (access key 4).
  • The tab order for all pages is consistent and designed for usability.


  • In cases where a link does not fully describe the target, the link contains a title describing it in greater detail.
  • A link containing the words “Web site” will open a new browser window linking the user to an external Web site.
  • Whenever possible, links have been written to clearly articulate the target when taken out of context. Many browsers, such as JAWS, Home Page Reader, Lynx, and Opera, can extract the links contained on a page to allow the user to browse the list separately from the page context.
  • Link text is never duplicated; two or more links containing the same text will always point to the same target.


  • All content images include descriptive ALT attributes. Purely decorative graphics include null ALT attributes (alt=””).

Visual Design

  • uses cascading style sheets for visual layout.
  • The content of each page is still readable even if the user’s browser or browsing device does not support style sheets.


  • Acronyms are identified by a dotted underline and have a descriptive title.
