I don't quite understand what you are asking for here. For looting you should use click to move and interact with target. If you bind interact to target on a key in wow (say G) and then make a hotkey in KeyClone (for instance alt-g) that broadcasts G to all slaved then they will loot the target if in range. Click to move makes them walk over to the target if it's out of range.

This also works for skinning, turning in quests and any other item in the world that you can select. I doesn't work on picking up stuff from the ground though. For that you have to either switch windows and do it one by one (is what I do), or make a key that sets the camera to the same view on all characters and use clickbroadcasting to loot (I never got this working in a satisfactory manner).

Not sure if this answer is of any use to you.
