I'd like a macro, which will turn a Felguards taunt (Anguish) ability on and off.
It can be two macro's, as easily as one, or with mod arguements.

So far, if I keybind the respective "Secondary Action Button", it acts as if I have left clicked it.
Similarly, if I call the spell by name, it casts it once, but does not turn it on for auto casts.

Is there a way to do this, short of right clicking on the pet bar or pet spell page?
