The stuff on the Wiki isn't very specific, but there are some good posts on this topic. I'll post mine when I get to a computer with WoW on it. Basically, it's like this.

key Pally Shaman
1 Avengers Shield Target pally if no target, target target of pally, cast purge
2 cast seq with holy shield, wisdom judgement and hammer of righteous nomod /cast LB mod:shift /cast CL (my healer will spam chain heal on this or button 1)
3 nothing focus, assist macro
4 another judgement (depends on the situation) cast seq of Earth Shock, Frost Shock and Flame Shock
5 Hammer of Justice all cast lhw on pally or his target

The other buttons are incidental, stuff like Thunderstorm and my totem drop macros.

Hope this helps. I'll try to post my macros later, but they need to be cleaned up. I am considering switching from the focus system to the FTL system.
