Toggle Through The Blend Modes
When I’m struggling to get just the right effect by changing the layer blend modes, it’s great to be able to rotate through each mode without having to go back to the layer blend mode pop-down menu every time. To do this, simply switch to the Move tool (V), then press Shift–+ (Plus Sign). Every time you press it, it goes to the next blend mode.
it does not work for me, what is it?
