[BRLTTY] BrailleSense QWERTY

[Vincent LE GOFF]

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
