Could you also share the desired, or perhaps more importantly, the current 
behavior with desk-top Windows modal dialogs? 
Understanding how JAWS or NVDA (versions please) behaves with Windows (and 
version please) desktop implementations can give us better insight into 
what is the browser's responsibility, verses the web page (UI Toolkit) 
responsibility, verses the screen reader's responsibility, verses the end 
user's settings (or configuration).

I thought I heard at CSUN 2014 from Shadi that there was an effort to 
publish techniques with an ability to document behavior findings by 
platform, browser, and AT.  Seems to me that a modal dialog would be a 
good candidate for the effort, but I can't seem to find the effort on the 
highlights archive:

and any difference with DoJo's modal implementation? see

Subject:        Dialog behaviour and screen readers


Dialogs have always been, and continue to be, an issue when using a screen
reader, with many implementations across the wide variety of widget 
of varying quality.

The best implementation I've seen so far is the Jquery UI dialog at:


This works very well for the most part, reading the dialog text and only
allowing navigation within the dialog using NVDA with FF. However, if I
interrupt speech before NVDA has read all the text, or if I want to listen
to the content again once the content has been read, there doesn't seem to
be any way for me to access the content again, short of cancelling the
dialog and triggering it again that is.

Is there a reference implementation for this problem anywhere? 

Is it simply a case of adding tabindex="0" to the title and content of the
dialog sited above to enable the content to be accessed again?
