Just to be clear, unbinding the keys in WoW on the clone(s) doesn't make CloneKeys not send those keys, but just makes WoW ignore them.

The Toggle of broadcasting with F15 is probably the feature you were looking for. BTW... that's the major difference between 0.1 (that only 2 others saw) and 0.2... Better preferences, the override hotkey works now, and a better about box.
