Detect autocasting

[Gost]

How do your detect when a hero right clicks an ability to being auto-casting?

I dont think you can detect when he Double-clicks.
But you can do it when he activates that ability.

Event-Unit starts casting an ability
Condition-Ability being cast equal to (ability you want)
Action-Whatever you want

Yea i know how to detect the casting of an ability, i was wondering how i detect the activation of autocasting for an ability. And nother question i already have my heros attack set to 0 - 0 (he does damage with abilities based on cold arrows) but in order for me to have a ability with a 2 second cooldown and a .25 second cooldown he needs to have an attack speed of at least .25 or faster (cold arrows only casts when your hero attacks) now the problem is for the 2 second cooldown ability: he only does damage every two seconds when activated but he attacks like 30 times (doing no damage) in between the ability enhanced attack, any way to fix this?
