How to playback all notes at a position, when clicking with mouse?

Hi all,

I guess this is a basic feature (or not available), however I have not been able to find it in any documentation.

When you have a song and click on an existing note, the sound of the note/instrument is played back. This is perfect, but what I would like is a way to play all notes that exists at the same position in the staff (even for different instruments). Is this possible? The reason is mainly to listen to and test different chords and voicings when composing music.

Cheers,
Kalle
