There is no help on looting, getting quests (you can get with one alt and share though), interacting with NPC (quest), or touching objects. Blizzard isn't likely to help on that because that might make things too easy to automate. I use seperate computers, so it isn't so bad for me. You might check on seperate screens or at least have them 2-3 on the same screen so you don't have to go in the background to do things on other alts.
