Re: testing the CanvasEditor attachment with JAWS12 and IE9 beta (was: Reworked Canvas 2D API using our revised DrawFocusRing)

aloha, charles!

ah, so you were working off the Freedom Scientific ARIA implementation
report -- gotcha...

the application role is a swtich, though, not a landmark, as defined at:

http://www.w3.org/WAI/PF/aria/roles#application

QUOTE
When a user navigates an element assigned the role of application,
assistive technologies that typically intercept standard keyboard events
SHOULD switch to an application browsing mode, and pass keyboard events
through to the web application. The intent is to hint to certain assistive
technologies to switch from normal browsing mode into a mode more
appropriate for interacting with a web application; some user agents have
a browse navigation mode where keys, such as up and down arrows, are used
to browse the document, and this native behavior prevents the use of these
keys by a web application.
UNQUOTE

which is why i expected the JAWS-reported landmark to be "form"

http://www.w3.org/WAI/PF/aria/roles#form

QUOTE
A landmark region that contains a collection of items and objects that, as
a whole, combine to create a form. Also see search.

[...]

User agents SHOULD treat elements with the role of form as navigational
landmarks.
