i used keyclone for multiboxing and within the keyclone program you can put a do not pass wasd (i added tab as well) and what that does it whatever window has control e.i. your mouse attention will have all the functions of a standalone and not pass said keys to the other toon and then just on the other toon make a macro just for him/her to follow the slave in this case. that's how i have it set up on mine and i've all been messing around with the 'interact with object' hot key for a macro for a slave to loot with.
