Re: [orca-list] How can I force Orca into focus mode?

[Nolan Darilek <nolan thewordnerd info>]

Orca isn't doing anything wrong. I'm rendering a 2-D game to a canvas 
element. I'd like to figure out if I can force a switch to focus mode 
somehow, so arrows and keyboard commands are intercepted by the canvas 
and control the game character rather than navigating around the screen.


Does `role="application"` force focus mode? Or if it doesn't, would it 
make sense for it to do so? Maybe I can wrap the canvas in that, or set 
that as its role. I'd try myself, but won't be in a position to do so 
until tomorrow.


Thanks.
