Yes. Or more precisely: they all expose a text interface, even if they
don't have a text role. Since apparently orca doesn't capture routing
key events, these events fall back to being exposed to the a2 driver,
which gives it to brltty, which uses a2 to read the widget content, and
perform the cursor routing.

If Orca was capturing routing key events, yes. It appears that doesn't
happen.
In the test I made with Roberto's case, it really was brltty's way of
pressing arrows to simulate routing, that Orca doesn't implement anyway.

Ah, that part seems odd however, indeed.
But again, which version of brltty are you using?

If that is so, it's a bug that needs a fix in Orca, and not just make
people install brltty-x11 as a workaround that we don't even understand
how it happens to work.
