>I can turn off talkback and still use braille?
Yes. One thing you should be aware of is that TalkBack handles the touch
exploration gestures. Brltty doesn't handle them. So, if you'd like the touch
exploration gestures to work then you need TalkBack running. With brltty, there
are other ways to handle accessibility focus, clicking, etc. You just navigate
the braille display to the screen element you want and press a routing key
associated with that element to act on it. That's why brltty doesn't need to
handle the touch exploration gestures.
The way the routing keys work is as follows. If you press the first (leftmost)
routing key above a screen element then it sets accessibility focus to that
element. The second routing key clicks on the element. The third routing key
does a long click. The fourth routing key scrolls backward, and the fifth
routing key scrolls forward. You don't need accessibility focus on an element
in order to perform ations like clicking and scrolling - just press the correct
routing key and the action will happen.
Brltty and TalkBack cooperate well together if they're both running since they
both use accessibility focus. If you perform any of TalkBack's touch
exploration gestures, brltty will move your braille display right along with
them. If you press the first routing key above an element, TalBack will jump to
that element, too. The braille cursor is on the element which currently has
accessibility focus, which works very well for cursor tracking and cursor
routing.
The cursor is usually on the first character of a screen element. If, however,
you're within an editable text area then the cursor as well as the routing keys
work as you'd expect them to when editing text. The routing keys route the
cursor to the desired character (rather than click, scroll, or whatever), and
the cursor is where input will go.
