Many web browsers support quick navigation using keys defined on the website. In Firefox versions 2 and later, you can press ALT + Shift + an access key. In most other Windows browsers, you can press ALT + an access key; on Macintosh you can press Control + an access key. All the pages on this site define the following access keys:
- Access key 1: Front page
- Access key 3: Site Map
- Access key 4: Search
- Access key 9: Contact me
- Access key 0: Accessibility statement
Although there are no agreed standards for which keys should be assigned to which features, all of these access key assignments do follow common conventions, and so are likely to be similar to the assignments on other websites designed for accessibility.
- All pages on this website are Bobby AAA Approved, complying with all the Bobby guidelines. I should warn you that this is a judgment call: many accessibility features can be quantified and tested, but many others cannot. I have reviewed all the guidelines and believe that all these pages are in compliance.
- All pages on this website are WCAG AAA approved, complying with all priority 1, 2, and 3 guidelines of the W3C Web Content Accessibility Guidelines 1.0. This is also a judgment call: many guidelines cannot be tested automatically, and indeed some are intentionally vague. I have reviewed the guidelines and believe that all these pages are in full compliance.
- All pages on this site are Section 508 approved, complying with all of the U.S. Federal Government Section 508 Guidelines. Once again, a judgment call; I have reviewed the guidelines, and believe that all these pages comply.
- All pages on this website conform to open web standards for XHTML 1.1 and CSS 3. This is not a judgment call: automated programs can determine with 100% accuracy whether or not a page validates according to the XHTML and CSS standards. All pages are checked with the W3C’s (X)HTML validator and CSS validator).
- All pages on this website use structured semantic markup.
h1tags are used for page titles,
h2tags for post titles,
h3tags for subtitles and section titles. For example, on this page, JAWS users can skip to the next section within the accessibility statement by pressing ALT+INSERT+3.
- All pages have links for
up, and (where applicable)
nextdefined to aid navigation in text-only browsers.
- All pages include a search box, and a link to a stand-alone search page (access key 4).
- This site uses Cascading Style Sheets for visual layout (but is designed to be readable even if your web browser or web browsing device does not support stylesheets at all).
- The color schemes used on this site have been checked (using Vischeck) for accessibility to the color-blind.
- This site uses only relative font sizes, compatible with the user-specified
text-sizeoption in visual browsers.
- Most links have a title attribute which describes the link in greater detail, unless the text of the link already fully describes the target (such as the headline of an article).
- Links are written to make sense out of context.
- All content images used on this website include
ALTattributes that substitute for the content of the image as accurately as possible. Purely decorative graphics include empty
ALTattributes (to avoid cluttering up the reading or the layout of the page in alternative browsers).
- Complex images include
LONGDESCattributes or inline descriptions to explain the significance of each image to non-visual readers.
