- output dots ... chord, when we don't have a mapping and a user presses a chord combination
- when a user types a dot pattern, back-translate the pattern using the current braille table and output.
For example, if a user presses dot 4 in English computer braille, they will hear "@".
- when a user types a chord that maps to a command or modifier, they will receive that as output.
For example, "control" (dots 2-5 chord), "backspace" (dot 7 chord)
