Re: [EXTERNAL] Navigation in application mode

I would go with a grid
http://www.w3.org/TR/wai-aria-practices-1.1/#grid
Once inside a grid the screen reader should automatically switch to
application/forms mode passing keys through to the webpage.
Then you can set up keyboard listeners to respond to the arrow key presses.
For the JQuery script see this example of an accessible date picker:
https://dequeuniversity.com/library/aria/date-pickers/sf-date-picker
I workd with a developer to create this. As it was done in 2014 when
the grid role was poorly supported we used role="application" to force
the application mode, I believe that is no longer necessary.
