Hi I'm new to multibox and macros but so far it doesn't seem to bad. I just wanted to post how I have my setup now and see if anyone has suggestions for simplifications. I'm multiboxing a 5 team of Pally, 3 Shamans, and a Priest. I'm using HKN, which I think is awesome, for a targetless, focusless, leaderless setup. So here's my setup:

Pally attacks: 1-0
Shaman attacks: q-z around wasd
Shaman heals and totems: Numpad1 - 9
Priest healing: Mouseclicking

I also have various keys bound for formation movement (v), follow (spacebar), drink/eat (=), smartbuff addon (numpad0), and eventually CC (most likely numpad buttons).
I'm curious to know if someone has figured out a toggle for formation movement and follow or raid icon targeting using the jamba addon.

I was debating putting this in here since it's so long but I did anyway. Parts of the code were taken off HKN website and midified, and the leaderless setup was taken from Anemo's Guide
[HotKeyNet] Leaderless setup with HotKeyNet
Maybe my code can help someone out. (I don't know how to add the scroll for the code, someone help me out)
