Create a layer with a mask.

In the layers dialog you will see black outline around the layer
preview and white outline around mask preview.

Right-click, choose Show Layer Mask. The mask preview will get green outline.

Right-click, choose Disable Layer Mask. The mask preview will get red outline.

There you are.
