Adding support for keyboard navigation and WAI-ARIA would allow Qooxdoo to be
usable by people with disabilities.
There is information on WAI-ARIA at http://codetalks.org
Please see the resource page on that site:
http://wiki.codetalks.org/wiki/index.php/ARIA_Resources (there's even an
in-depth video now)
There are also plenty of examples:
http://wiki.codetalks.org/wiki/index.php/Set_of_ARIA_Test_Cases
I also really suggest signing up to the mailing list for support:
http://groups.google.com/group/free-aria
Other JS toolkits either already have support for WAI-ARIA or are currently
planning it. Dojo currently has the most complete support, followed by YUI,
then GWT, then JQuery.
On the browser side, Firefox 3 has very complete support. IE 8 betas have basic
support, and both WebKit and Opera have added some support for ARIA.
Sorry, obviously I meant to say Gara.
