As my other tutorials have shown, I’m fond of Photoshop layer-styles. For skinning projects, however, large amounts of layers may be required to accommodate the various layer-styles (I have some files for skins that use between 400-1000 layers). When there are many styled layers working in conjunction, it may become difficult to determine at a glance what the actual contents of a layer are or its location. This is especially true of compositions including lots of Stroke, Outer Bevel, Drop Shadow, and Outer Glow styles.
To counteract this problem for myself, I devised two simple actions that quickly became my personal favorites.

Hiding all layer-styles
Showing all layer-styles
I’ve created actions for these so that the F11 key hides all layer-styles and F12 shows all effects. Again, these options only work when you have a visible layer selected, not a layer-folder or hidden layer.
