>I know this has been answered many, many times on this list and David is

Oh, I'm very unhappy for sure! :-)

>but I can't seem to find the proper process.

That isn't a crime. :-)

>I've finally acquired a small computer running Linux, have installed BRLTTY
>(5.6) 

Why such an old release? I doubt that's the cause of your problem, but I'm
still curious as to why one wouldn't install the latest.

>This was a modified version of the file found in 'Tables/Input/ht/rockers.kti'

That's risky. You should always use files from the same release that you're
running. Again, in this case, I don't think it'd be much of a problem.

>Hu, where to place this modified file?  So I looked up readme.customize and

Yes, that's the right place to put it.

>So I wrote the file in /etc/xdg/brltty/rockers.kti, rebooted my little

In a case like this, the log is usually your friend. Use brltty's -L
(uppercase) option to write its log to a known file, and then post it so that
we can have a llok. For example:

   brltty -L/tmp/brltty.log

Adding -ldeubg (this l is lowercase) would also be helpful.
