LF auto-assist macro!

hey all, i need a little help with this one.

basically, everyone knows when dual boxing that all toons that are following the main char must have "assist" macros on them. i am looking for a macro that allows me to not have to hit the "assist target" macro every time a new mob is targeted. I am not quite sure if the focus macros could be arranged to this or not. I'm slightly new but have an idea of coding and what not so please bear with me.

Example:
I have two warlocks running on keyclone and am looking for a macro in which [warlock #2] can target [warlock #1] and auto-select his target to cast per-say....a shadowbolt onto. [warlock #1] targets a new mob thereafter and [warlock #2] auto-targets it. I want this macro to work so that i should not have to press it for every mob, but instead only one time to activate it.

i have been looking for such a macro on all types of forums and just finally decided to post a new topic here to see if the community could help me out. Thank you very very much all.[/b]

It's pretty easy:

Step 1: Make macros to set each player as /focus. "/target Char1; /focus" "/target Char2; /focus" etc. Bind these to easily accessible keys (I use F1-F4)

Step 2: Make all your macros for DPS like this... "/cast [target=focustarget] Shadowbolt"

This will do exactly as you said in your post... you're running along with your "main" and you spot a mob. You target that mob, stop in place, hit the button to cast shadowbolt, and blam.... both locks cast it.

If you're doing more than 2 characters, and one dies, you can just hit one of your F1-F4 keys to change the focus to another player and keep on fighting.
