Access Keys
Most browsers support jumping to specific links by typing keys defined on the web site. On Windows, you can press ALT + an access key, then ENTER; on Macintosh, you can press Control + an access key.
Pages on this site define the following access keys:
- Access key 1 - Introduction
- Access key 3 - Summary
- Access key 5 - Sample RealAudio Files
- Access key 6 - Sample mp3 Files
- Access key 7 - Sample Ogg Vorbis Files
- Access key 8 - Sample Windows Media Files
- Access key 0 - Accessibility Statement
Standards Compliance
- All pages on this site are Bobby AAA Approved, complying with Web Content Accessibility Guidelines 1.0 and U.S. Section 508 Guidelines. This is always a judgement call; many accessibility features can be measured, but many can not. I have reviewed all the guidelines and believe that all these pages are in compliance.
- All pages on this site validate as XHTML 1.0 Strict. This is not a judgement call; a program can determine with 100% accuracy whether a page is valid XHTML. For example, check the home page for XHTML validity.
- All pages on this site use structured semantic markup. H2 tags are used for main titles, H3 tags for subtitles. For example, on this page, JAWS users can skip to the next section within the accessibility statement by pressing ALT+INSERT+3.
Navigation Aids
All pages have rel=previous, next, and home links to aid navigation in text-only browsers. Netscape 6+ and 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).
Links
- Many links have title attributes which describe the link in greater detail, unless the text of the link already fully describes the target (such as the headline of an article).
- Whever possible, links are written to make sense out of context. Many browsers (such as JAWS, Home Page Reader, Lynx, and Opera) can extract the list of links on a page and allow the user to browse the list, separately from the page.
- Link text is never duplicated; two links with the same link text always point to the same address.
- There are no "javascript:" pseudo-links. All links can be followed in any browser, even if scripting is turned off.
- There are no links that open new windows without warning.
Visual Design
- This site uses a cascading style sheet for visual layout.
- This site uses only relative font sizes, compatible with the user-specified "text size" option in visual browsers.
- If your browser or browsing device does not support stylesheets at all, the content of each page is still readable.
