What are you wanting to know? Once you read the stuff on the Keyclone site http://solidice.com/keyclone/, read the FAQ's and watch the video's it's pretty simple. You turn the program on, set up some command in the command editor (so Keyclone will know which copies of wow to open when) and then in the pull down box on the main Keyclone screen type in the commands you want to run. For example:

I have 5 chars I want to play; Fred, Bill, Bob, John and Ted. I go to setup, command editor and I make a command titled each of those names. I tell it what program to use (i.e. what copy of WoW to open), what keymap (if any, I don't use one currently) and what region (if you use maximizer, which you prolly should). Once all 5 are added I click ok and at the main screen, in the pull down, i type fred;bill;bob;john;ted and hit connect. That is how you do it for all clients on one machine but the info is there. Most this is on the http://solidice.com/keyclone/ site.
