When I’m in note input and I edit a duration (Ctrl-Z, or Shift-Alt-L/R), the caret advances to the correct spot for me to continue note entry.
It doesn’t always work for Ctrl-Alt-Shift-L/R, however. Sometimes it advances correctly, sometimes it doesn’t and I have to move it manually, which throws me off. Seems like a bug.
I was able to reproduce one example where the caret doesn’t advance when Ctrl-Alt-Shift-Left arrow is used, and it has to be moved manually:
