Shortcut for Routing Selected Channels to the same Output

I remember seeing a thread or video of tips, and one really helpful one was being able to select a number of tracks, and then holding something down and changing the output on one of tracks would then apply to them all. Almost like a quick linking and selecting the same output.

Does anyone remember this shortcut?

Shift+Alt.

AWESOME thanks! Do you remember where this little tip was? I would love to see more of these!
