Hi,
Good news! I have been able to log the four navigation keys. I hope
the information is useful, even though to me it looks like 4 unknown
keys have been pressed and released. I hope it helps. See the log file
attached to this email. Here's the more detailed description:
The BrailleSense (either QWERTY or Braille) has four navigation keys,
two on each side of the Braille display. I pressed the upper-left one
first, released it, then pressed the lower-left one (just below the
previous one). I repeated the same process on the right: first the
upper-right key, then the lower-right. Those four keys are used to
offer different navigation modes and I must admit it's not always the
same in all screen readers. On the BrailleSense itself (which may look
like the right basis to look at), here's the key mapping. I will refer
to key 1 (upper-left), 2 (lower-left), 3 (upper-right) and 4
(lower-right), hoping it's not too confusing:
Key 1: Backward a Braille window.
Key 2: Backward a whole line (similar to the 'up' arrow, but it doesn't
move the cursor).
Key 3: Forward a whole line (similar to the 'down' arrow key).
Key 4: Forward a Braille window.
As you can see, the key 1 (upper-left) and key 4 (lower right) are used
to move from Braille window to Braille window, which is the most common
use-case. Several screen readers tend to have a different behavior (for
some, key 1 is backward a line and key 2 is backward a window) but I've
used the HIMS mapping in this description.
Finally, I would point out that some keys aren't mapped yet, including
(and most importantly) the preferences. It would be great to have a key
mapped to this BRLTTY command. I haven't included it in the log, I
don't know what I should use and I didn't mean to get it too complicated
at once, so I'll wait for your reply to do another test if appropriate.
If something isn't clear, don't hesitate to ask more questions.
I hope that helped,
Vincent

I'm running Vinux on a virtual machine (perhaps the probem comes from here,
but I don't think so).
No, it isn't. Those keys aren't supported yet.
Here's what my log was filled with. I guess I should have stopped
BRLTTY before running the 'sudo brltty -L/path/to/log/file
/linputs.brlkeys' command, but I don't know how to do that:
Do you know where the command line that invokes brltty is? If so, perhaps you
could update it with the two options and then reboot.
Alternatively, it may be configured via /etc/brltty.conf. If so, then you can
achieve the same by adding these two lines to it and then rebooting:
log-file /path/to/logfile
log-level inpkts,brlkeys
