Tyval, the difference here is that the guy you're trying to copy isn't using the standard Interact with Target mapped key generated by the wizard -- he has CTM enabled for the slaves when he switches (e.g. what universal said). The standard IWT key turns it on only for a moment, and requires multiple steps. That's not going to work right in your case because a Do Mapped Key Action is only going to execute the first step of the IWT mapped key. Technically you can add a second Do Mapped Key Action to execute the second step (which turns CTM back off).
