We use enough properties of the LEFT/RIGHT kind ((2) and (3) are really the same option apart from examples/docs) that I don't see a reason to diverge here. A property 'handedness set to LEFT or RIGHT would be in that ballpark. It's similar to text-direction. > https://codereview.appspot.com/339270043/ -- David Kastrup _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
