Forum:Quick-Play Spells?

Hey, I'm new to this wikia thing but not to Yugioh. I'm wondering, when can you activate quick plays? I think that you can activate them anytime from your hand during "your" turn and if you set them you may activate them during your opponent's turn like a trap card provided the requirements are meant for activation. My friends think you can activate a quick-play from your hand even though it's your opponent's turn. Clarification, anyone? Arigato.
