Moving tracks independently

I have two separate stereo sources, i.e. four tracks. I want to select the bottom two tracks and move them to the right and do a cross fade.But when I use that horizontal double-arrow tool (whatever it’s called), all I seem to be able to do is move ALL the tracks. I’m sure what I want to do is covered in the manual, but darned if I can find it. Please help?

Never mind, I finally figured it out!
