User Agent and Assistive Technology Support Notes
Home Page Reader, JAWS, and WindowEyes all provide navigation via headings
and provide information about the level of the heading. The Opera browser
provides a mechanism to navigate by headings. Additional plugins support
navigation by headings in other user agents.
The objective of this technique is to demonstrate how using the heading
elements, h and h1 - h6, to markup the beginning of each section in the
content can assist in navigation. Most assistive technologies and many
user agents provide a mechanism to navigate by heading elements by providing
keyboard commands that allow users to jump from one heading to the next.
Using heading elements to markup sections of a document allows users to
easily navigate from section to section.
