[BRLTTY] Confusion with keys. names.

[Fabrizio Marini]

Hi all.
I'm really a newbye in Linux and I'm reading a lot of documentation 
to get better.
My braille display is an Alva Satellite and I'm encountering 
difficulties in understanding how the documents I read refer to  the 
Satellite's keys.
Here's an example. The brltty reference manual gives his own names to 
the keys (e.g. WINUP, LNUP, ETC.) and suggests the reader to refer to 
the Braille Driver manual to know how those keys are maped on the 
braille display.
So, I red the documentation about Alva braille driver (the 
Alva.README file), but I haven't found which keys correspond to WINUP 
and LNUP.
Also, on Alva.README, keys f1b and f2b are mentioned, but it's 
impossible to know which keys these names correspond to.
Is there any document I should read to solve these problems?

Thank you so much and have a nice day.

Fabrizio.
