I have compiled the latest code and run it. Since I was not able to make any
adjustments in the preferences menu, I switched back to the old version. Then I
decided again to give it a try and as soon as the new BRLTTY was started, the
error occured and I had a locked caps lock key.

What is the correct key to press in order to open a menu item in the preferences
menu? In 5.1, I always used the Routing Keys. Which key is mapped for this? Is
there documentation about the key bindings except for reading the key tables
themselves? Would it be an idea to write a script (if not already done), which
parses those files and generates an overview with the key combination, the
function name and a description? I imagine that the function names like LNDN
etc. are documented somewhere and such a script wouldn't be hard to write. If
this is indeed not implemented yet, I would implement even such a script.

To be honest, I only switch BRLTTY due to missing profile support which is in
turn only needed for language switching. If I turn off speech, there's no
reason. But I will have a look at automated restarts of BRLTTY with no speech.

Thanks
Sebastian
