I have been online chat with support and just found out this is NOT supported in the MAC version!!!! I am REALLY disappointed in this very simple operation being overlooked. One of my main reasons for purchase was to create exercises around the circle where I could just put the chords in the first key then "copy down" and have this program put it in the other keys. Evidently this is easy in the windows version but not supported on MAC........... Not a happy customer..
