How to Multi Table

I'm wondering if there are any tricks to multi-tabling. I usually play 2 or maybe 3 PP 10+1s at a time. During most hands I've got a decent amount of dead time when I read 2+2, watch TV, mess with PokerAce, etc. However, every now and again when I pick up a couple of decent hands at one time, I can be a bit pushed to get all of my raising/calling/checking/calculating pot odds done. I feel like I might be able to handle 4 at once, but any more than that and I think that I'd be completely lost as to what to do when I get AK, QQ, 88 at once. This is especially true of hands that require a bit more attention to play such as SCs, medium PPs, AJ-A9, and so on.

Is there some sort of strategy that doesn't require as much thought or that directs actions more exactly. In other words, are there some tricks or strategies to playing 6-12 or more tables at once?

Thanks,
Will
