I have a question regarding the program Keyclone which basically is used by
people to control multiple programs with a single keyboard and mouse on the
same computer or multiple computers.

First of all, are there any alternatives to Keyclone for a single machine
application. I am aware of Synergy, unfortunately I my other machine is
incapable of actually running World of Warcraft which is the intended
program.

Second, if there are no alternatives to Keyclone, do I actually have to
purchase it to get it to work, or can I operate with restricted features
before purchase to see if it meets my needs.

I have been to dual-boxing.com and quite frankly I don't understand half of
what they are saying. Keyclone is so ungodly non intuitive that if it wasn't
for the fact that I have 2 accounts I would never think of using it.
