Spontaneous switching between note- and chord-playback

I love the option to have chords playing back when clicking on them so I have this activated all the time.
However sometimes I prefer spontaneaous note playback e.g. when editing single notes in a chord. Pressing Alt/Ctrl/Shift or the like has no effect here.
Is there a solution ?

No, I’m afraid there’s no way to do this other than changing the setting in the Preferences dialog.
