Hi Jon,

Many thank for the comprehensive reply - it's very useful.

Is this is a common or well known approach (do you find) to enabling
keyboard a11y for many users? From the user perspective it seems clunky
in that, when using a keyboard in a regular website or application - if
elements are links/inputs etc, or via simple tabindex magic then voila.
IMO, many people who could benefit from keyboard a11y for apps may not
likely have a clue what VO is.

Right.

Yes. I was aware that for Switches/scanning applications they consume
the same semantics via the API/UIAccessibility protocol etc. Interesting
that you refer to it as a 'keyboard interface'. Actually, this kind of
thinking is useful as it is common to think of A11y APIs being only for
SR users, or at least they are the most complex but the delta between
other ATs that can usefully consume those APIs is where more inclusive
design happens I guess.

Exactly, good point. That is what I was thinking, and it should be
trivial. There are certainly common use cases for many users who would
benefit from keyboard access to the UI on mobile/tablet devices.

Right, out of the box. I've found native Android apps to have better
keyboard a11y.

Agreed. It's good to see Android ahead of the curve with this modality
:-)

Appreciate the feedback Jon, thanks.
