on yoru primary machine, make sure keyclone is running

on your secondary keyclone, go to keyclone/setup/general
put the ip and port (iport) of your primary keyclone in the auto-connect box
check 'auto-connect'
go to the nickname field, at the top of the panel, and set the nickname to B (or whatever).
hit Ok.
exit keyclone and restart (this will insure nickname is pushed properly)

now, when your secondary connects, it should show a nickname in the keyclone list on your primary.

to test running your macro, you can type B:wow2 on your primary keyclone and hit enter (or click 'connect')... this should launch wow2 on your secondary machine
