Hey dude, I'm kinda new to this community myself but ill do my best to help you out.

If u can afford it, get KeyClone. It's a one time payment software, and the easiest one out there to broadcast ur keystrokes. If you cant afford KeyClone you should get AutoHotKey, which has a great guide on how to setup ur first script and you can even download a script which has all main keys already bound.

Checkout Addons and Macros Forum also and equip ya'self with some interface and questing addons (so the alt will auto follow and auto accept invites and quests).

GOOD LUCK!
