alto clef bug

Hi, I’m using 3.5 pro and I think I’m experiencing a bug when trying to enter an alto clef. I am inputting “C” into the popover and getting nothing. Typing alto does work though.

C clef can be any number of clefs, such as tenor or soprano. It’s a category, not a specific clef. CA works. As does “alto,” as you noted.

The C clef can be on any line of the staff, so just “C” is ambiguous.

C3 works for the alto clef, and C4 for the tenor.
