I have an iMac and I want to get the X-Keys Pro USB 58.

Will I be able to control multiple instances of WoW with the X-Keys Pro USB 58 in the same fashion that I can control multiple instances with my keyboard while using clonekeys?

Are there any other additional key hardware devices that can accomplish this on a Mac, IE competing hardware to X-Keys? And, even if there was, which would be recommended?

Thanks in advanced.
