Keyboard teases you with characters that are not allowed in song names

Cannot type various symbols int the song name. Suspect this is because the song name must also be a legal filename.

If we can’t use 'em, please gray them out or remove them frok the keyboard.

FYI, since we have no other place to record notes like the BB rhythm and bpm. it’s nice to have a few characters to seperate these from the song name like "Song Name (Blues 6 6/8 82 bpm)

Not the highest priority.
