Hi Crovean,

Welcome to Multi-Boxing!

I use Synergy myself (make sure you get the keyboard broadcaster version listed here), but you might also want to try the multibox software.

As to keys - the easiest way to have Shift-1 activate your alt is to bind the Shift-1 key to action bar slot 1 on your second machine, and un-bind it from your main machine. That way, your main will ignore the keypress but your alt will take action.

Other things to watch... Synergy broadcasts all keys (unlike multibox which can broadcast only some keys), so you'll need to un-bind the movement keys on your second computer. I unbind qweasd on the alt (so I can use them for my main movement) and unbind the arrow keys on the main computer (so these now control my alt).

I also setup bind a key to turn on and off Synergy keyboard broadcasting (so stuff in chat isn't said by both characters simultaneously) and another key to run a 'follow main' macro.

Finally, I set a Synergy hotkey (as described here) to 'stay on one screen' when the right mouse is pressed. Without this, you won't be able to use the mouse to position the camera on your second computer.

Good luck!

David.
