You already know the name of the Mapped Key so you can look for it in ISBoxer. Once you find it you can either use the existing Hotkey or change it. By default, JAMBA strobing is Shift+Alt+F (Unless we're not talking about Strobing?).

You can create a Clickbar for it as well by just creating a new Clickbar, having it tied to that particular Mapped Key, and setting the target as Window:Current.
