Where is the "simulate control" action?

So I want to make my enemies move in a simple platformer and the tutorials mention a "simulate control" action, which I can't find anywhere. Where is it located?

Insert the "Platform" behavior into the enemy sprites (f you have more than one enemy sprites, make a family for them and insert the behavior there).

Add an event and check for the "Simulate control" action in the "Platform" section when adding actions.
