The Duplicate Layer command adds a new layer to the image which is identical copy of the active layer. The name of the new layer is the same as the name of the original layer, but with “ copy” appended to it.
You can create a duplicate layer by clicking image menu→ Layer → Duplicate Layer, or from the local pop-up menu that you get by right-clicking on the Layer Dialog.
A Copy of your previous layer will be automatically made in the Layers tab.
