'Knockout' is a blending option, turning a layer to a kind of a mask for all underlying layers except for the Background layer. To create this effect: • Choose a layer in the Layers palette. (On this screenshot - 'Shape 1') • In the Effects palette, double-click the 'Knockout' thumbnail. • If you want to punch through the Background (to transparency), convert it to regular layer (Layer > New > Layer from Background) or simply hide it (screenshot). • To turn off the effect double-click the 'Disable Knockout' pictogram in the Effects palette. When you apply the 'Knockout' to a shape layer, the Custom Shape and other shape tools tend to remember the effect and apply it to follow-up shape layers.
