[Quetion] Is there a papyrus event firing when an idle marker begins / stops getting used?

[Antono]

Fellow modders,

 

I need to know when an actor begins using an idle marker and when she stops using it. Is there an event firing when this happens?

 

OnActivate could be the one firing at the start. Is it? But what is the one firing at the end, if any?

 

Or should I be looking at the OnAnimationEvent group?

 

Many thanks for your answers!
