Melodyne Studio- Creating Chords and/or harmony

[dnaflr2]

So all I wanna do is open a lead guitar or vocal line, select/copy the notes that are already there, and paste them to create a harmony.

Am I the only person that is pulling thier hair out trying to make this happen. I have traied key commands and went thru the menus, but no success. I k now I am overlokking something. It says on the tutorial to just click the original nore, hold down option and drag to new pitch, but this ain't workin.
