1. If you need to turn around fast, make your main run through your slaves. Faster than KB turning and less difficult than trying to turn via keyboard + cast. You may lose out on some cast time on your main, but if 5 can now cast instead of 1 thats a lot more pain.

2. There is a section, my memory is failing me at the moment but it's there, where you can bind keys to bypass D-N-P. Have a look through the options window, it has options for bypassing everything, from memory the first option at the top is to pause keyclone.

3. Cloning mouse movement I believe can't be done via Keyclone (or at least very well?). Your best bet is to get an addon such as Multiboxer V2, talk to the NPC on all characters and then go through the chat stuff on your main character. When set up to follow prompts from your main, all your slaves will hand in quests/accept quests/accept flight points/etc.

4. What type of attack? Melee? If so you're probably stuck with pushing a macro, as automation is considered bad (removed because of bots, thus bannable). /assist [target=focus] /startattack. If I need my shamans to attack I press (logitech mx518) the button above my scroll wheel with alt held down and they go into melee mode, then press it again without alt and they follow.

5. Ignore loot quests. It takes on average 5 or 6 quests to level, aim for escort, kill quests, delivery quests or loot quests with a 100% drop chance and you only need a small amount of items. Looting is all manual, as automatic looting would be automation, thus bannable again (bloody botters).
