Thanks Matt! I am not dong something complex in this case. Just slapping down a quick chord progression to practice guitar improvisation over. From your excellent detailed comments, I suspect that for this simple need, I would just leave the key menu set at C and plop down the chords in whatever starting key I want. Then I suppose IF I wanted to transpose the quick and dirty chord progression to another key so as to improvise over another key, but with the same function of the chords I wrote, then I would change the key setting in the drop down menu. Sound right? I appreciate your guidance and Merry Christmas to you.
