I dont know anything about keyclone but if you want a free program I use hotkeynet

here is my script that is complied from various ones listed on site. create this on a notepad file save run both wows run hotkeynet click load script then press ctrl + r it will rename and resize windows pluse setup keys and mouse clicking by clicking "~" then clicking on your screen it will click on slave as well. press F12 to switch between who is part of big screen. anywhere you see like F12 just change that to whatever you want if its easier. oh and I have capslockoff as the hotkey on and off button the main site says scroll lock on but I dont have scroll lock on my keyboard.
