Sometimes getting a perfect effect in your layer styles takes some work and patience. If you get that layer style exactly the way you want it, how do you duplicate that perfection onto another layer?

Hold down your alt/opt key and drag that layer style icon (fx) to the layer you want to apply that perfect layer style on.
