Re: Standardization of Keyboard Shortcuts

Hi Tim,

Have a look at WCAG 2.0 Failure F15, related to Success Criterion 4.1.2:
(Role, State, Value) . The description explains that the accessibility API
must be supported, otherwise:
"assistive technologies will not be able to understand what the control is
or how to operate it ..."

The problem is that the access technology may prompt users to use the Enter
key, which won't work if I understand you arright.

I came across another example of this type of dichotomy in recent testing
where a menu widget had been created, using ARIA, but the JavaScript
restricted access to open menu items to the tab key only. JAWS has a built
in prompt to "use up and down arrow keys" when it encounters an open menu.
The end result is that the user has no idea how to activate the control.

Hope this helps,
