Perhaps this could be solved by an overview page which describes each braille
display, the key layout, and links to the help file for the details.
Subscribers to this list who have access to various displays could contribute
the brief descriptions.

This is a good idea, but preferably not as the default. One of the advantages
of using BRLTTY is that one doesn't have to be concerned with possible
keyboard conflicts, pass-through keys and the related issues that speech
software has had to deal with for ever. Even if there is a key combination to
invoke help, the user still needs to know what keys to press on the braille
display to read the help text, unless those are mapped to keyboard cursor keys
as well.

Would a user-space mechanism for invoking help, and the preferences menu, be
useful? Clearly this would require protocol access to these functions.

Whatever is done, it would need to be documented in the README files of
installation media, installation manuals, etc., but that's an issue for the
distributions to sort out.
