Re: [orca-list] Cursor Tracking, Orca, and Braille

Hi John:
I think what might be nice is a way to have BrlTTY synthesize keyboard navigation keys (e.g., arrow, page up/down, and tab) so the user does not have to move their hands from the braille display in order to navigate content.
I started looking at this again about a month ago with Samual Thibault, and I believe the answer is to use xbrlapi in conjunction with brltty. The idea is that xbrlapi would interpret commands on the braille display and would then synthesize events for you. I'm not sure my braille display has enough buttons to let me generate arrow/page/tab keys, though.
If someone has been successful using xbrlapi to do this kind of thing, please let us know.

Using Brltty, you should be able to track the cursor, depending on the
display, put Brltty in learn mode and you should find a key
combination to follow the cursor.
