Use clicky to remove spells cooldown

[maxlaurent]

Hey,I heard a shaman saying that if u use a clicky, it removes the cooldown of your spell bar, u can for exemple use it to shrink faster.
I tried with a clicky on my chanter (rod if insidious glamour) after stunning a mob but it had no effect at all on my spells cooldown. Am I missing something ?
Thanks guys !
