Hi Ralph,
To copy and paste in ONLY the chord names,
- select the region of measures to copy like you normally do,
- Edit/Copy (or ctrl + c)
- select the region of measures you want to paste into
- NOW use Edit/Paste Special, then select "Paste Chord Names"
and viola*! You paste in only the chord names.
Enjoy
