An Easy One - Shortcut Command

PT 11; Win7/64

I am a PT vet who has never used certain shortcuts. If I have multiple instrument tracks, let's say six of them to pick a number, and I want to bus all of them to separate audio tracks, what is the shortcut that you use so that you don't have to go to the first track and bus 1-2, then the second track and 3-4, etc?I want that to happen automatically.

Thanks!
