How can i sync 2 accounts on WoW and play?

i can run them both at same time but its impossible to use them efficently since it makes you switch tween windows

and thats where the problem is, being able to control one char w/ the other

ie; playing window A and have char A use skill 1,

making char B use skill 1 w/o switching to window B...

i know its realy complicated, even if it sounds simple

but i know its possible, its a matter of if theres a program or such out there

i seen people doing this by using multiple computers one for each account and being able to control everything with one keyboard and mouse. but it is a huge investment for one game.
