To create a vector mask that reveals the entire layer, choose Layer > Vector Mask > Reveal All.
To create a vector mask that hides the entire layer, choose Layer > Vector Mask > Hide All.
Drag the vector mask thumbnail to the Delete
icon .
Select the layer containing the vector mask you want to delete, and choose Layer > Vector Mask > Delete.
Shift-click the vector mask thumbnail in the Layers palette.
Select the layer containing the vector mask you want to disable or enable, and choose Layer > Vector Mask > Disable or Layer > Vector Mask > Enable.
A red X appears over the mask thumbnail in the Layers palette when the mask is disabled, and the layer’s content appears without masking effects.
