Seperate action bar keybindings per character

Hi, I started using ISBoxer yesterday but am having a bit of trouble getting up set up comfortably. I have a Warrior (Tank) and Shaman (Heals) in my team, most of the stuff like following etc. works fine. However, what I would like to achieve is having keys 1 => 0 act as normal for my main window (the warrior) and then have ALT + 1 => 0 as the action bar buttons for the Shaman.

I copied the existing FTL DPS keys and modified them to their +ALT variant, however I can never get this to actually work in game. I also set up the Shaman's action bars so that the buttons I want to use are also mapped to e.g. ALT + 1 there. If I just leave it as the default, everything works fine and keypresses get passed through to the other window, but when I try and use the ALT+ versions, it doesn't work.

Sorry for rambling, I'm just worried I'm not explaining it well Thanks for any help anyone can give.

Well I figured it out My mistake was having copied, instead of using the Add Many Mapped Keys function as described here http://isboxer.com/wiki/WoW:Quick_Start ... uto-assist. The penny's finally dropped now on how to set up these keybindings Posting here for other people who may have had the same issue.

I'd probably go with pre-defined Action Target Groups.
Put your tank into one of them.
Put your shaman(s) into another.
Can call them Warrior and Shaman if you like.

Then change the targets accordingly, so 1 through = is sent to Target: Warrior (the Action Target Group).
And have the Alt + 1 through Alt + =, sent to Target: Shaman (the ATG).
