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

[Nolan Darilek <nolan thewordnerd info>]

Aside from landing on a form control, is there any way? Experimenting 
with building HTML 5 games, and having Orca trigger focus mode on my 
game canvas would be a nice quality-of-life improvement. Is there a role 
or other hint I can use to achieve this?


Thanks.
