Basic Editing Question

[jwd65]

Hi all,
I did my first serious slice and diceing in the editing window yesterday in cutting out entire parts of a demo song. I was pleased with the success but had to do it track by track (there were only three of them) in deleting sections and grabbing the following region and moving it forward.
My question: How do you move the region(s) following your deleted section(s) doing multiple tracks at the same time? (doing it the way I did--one at a time--if the tracks aren't lined up perfectly, there's a problem)

Any help appreciated,
J.D
