Could use a shortcut for soloing the track while in a playlist lane

[moshuajusic]

When I go through takes in playlists view, I often want to switch back n forth between hearing them in the mix and hearing them solo. I feel there should be a [something]-S for toggling the track's solo button while the cursor is in a playlist lane. Is there a way to do this currently? If not, I'll add it to ideascale and propose option-S (on Mac), since that seems to do nothing right now.
