Yes, I have looked at every example I can find, including the APG 

Dojo may have been screen reader tested. But, generally, screen reader 
testing is a very imprecise practice. I rarely see documentation of 
expected screen reader behavior for a tester to reference. When I do, it 
is not often correct. And, "correct" is sometimes a topic of intense 
discussion. The consistently reliable way to get good screen reader test 
results is to have it performed by a large group of blind and experienced 
screen reader users who have a nack for testing. Outside of that, the 
quality of results varies dramatically. So, I am pleasantly surprised when 
I hear the claim that screen reader testing was performed and then my 
experience is close to what I would expect. I do not get that pleasure

Hi Matt,

By "our example implementations", do you mean the example links in the 
APG, including the dojo links[1]?

This is a case where the combobox uses aria-activedescendant instead of 
roving focus.  Combobox is one of the few places where dojo uses 
aria-activedescendant.  By keeping focus on the edit field, as the user 
types, the characters are added to that edit field, and the dropdown 
list is updated to show just the items that match.  Functionally 
speaking, it is very similar to FireFox's location input (the "awesome 

But, I had thought dojo had tested their ARIA markup with ATs, and that 
it worked.  Cc'ing Becky...
