[BRLTTY] documentation for keyboard commands

[covici at ccs.covici.com]

Is there any documentation or a list of keyboard commands for the ALVA
bc640?  Things like space and dots 1-2 apparently toggle skip windo
on/off -- I did not see anything like this in the help text.  Maybe I
missed that.

Thanks in advance for all your help.
