Playing a selected line in modulation screen , is there a button?

Hi,

Went through the helpful but struck!

When in the modulation screen I know to toggle between the different lines by the key switches. When selected I like to play them. I know from the help file that a play-button should be there. I’m in limbo as how to trigger that as I cannot find it or a way to trigger ‘play’

welcome @Peterv
You can trigger the individual chords when you have the selected via key switch but you can’t play the chord progression in modulation mode. You can do this in the main window or edit mode.
