[BRLTTY] BrailleSense QWERTY

These keys must only be on newer Braille Sense models. They're also on the 
Braille Edge, though, from your log, I can see that they're mapped differently. 
That explans another mystery that I've been curious about, by the way.

Are you saying that that's what these keys actually do right now?

Older Braille Sense models had four keys that were known as either function or 
advance keys. I think they're more like bars. Does yours have these too, or not 
at all?

No, I can't see that from this log. If they're actually doing that then I'm 
wondering if your Braille Sense is actually presenting itself to the driver as 
a Braille Edge. Could you please add the usb and outpkts log categories, and 
send me a complete log so that I can see what happens when the device is 
probed?

Also, I think a lot of the special qwerty keys (arrows, page up/down, insert, 
delete, home/end, F1-12) may not be mapped. Could you please send me a log that 
shows what happens when you press them?

>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.  

There's a problem I need to think about a bit because I'm not sure how to 
determine which type of keyboard the device has. I'll be thinking about it 
while we make sure that all of the keys are working.
