As long as a track has an insertion cursor (that is, if you have the setting for "edit selection follows track selection—or whatever the exact phrase is—set in the Options menu), make the selection however you wish, with the num pad or up and down arrows, scrub wheel with the Shift key, etc. Perform the cut or copy action or whatever you wish to do. Now you need to navigate to the track within which you wish to paste. To do this, you need to use either control-semicolon to move down one track at a time or Control-p to move up one track at a time. Of course, if you think of it as tracks being left to right, well, Control-p moves to the left and Control-semicolon moves to the right. So, naturally, if you're moving to an adjacent track, it's very simple. If you're moving to a track that's 20 tracks away, it can get a little tricky. If you hide unnecessary tracks and just show the tracks you're interested in, then it technically becomes an adjacent track because all the tracks in between are hidden from the mix and edit window areas. Keep in mind that all tracks are always visible in the tables but not in the mixer and edit areas.
Hope that helps, Slau
