Re: [Denemo-devel] ReadingNoteNames Varaitions

[Richard Shann]

I've completed the documentation on the commands for querying the tag of
directives on notes, chords, standalone indeed on anything else (score
directives, or keysig directives... for the staff the cursor is on)
It should be trivial to do NextRehearsalMark, or NextTempoChange now,
(for examples).
