To duplicate a layer, select that layer in the Layers palette and choose Duplicate Layer from the Layers palette menu. The new, duplicate layer is placed directly in front of the original layer.

If you duplicate a story with linked text boxes that have been placed on different layers, you will observe the following behaviors:

• If you duplicate the layer containing the first box in the story, all of the text in that box, as well as the text in the linked boxes that complete the story, is duplicated. The first box displays on the duplicated layer and displays an overflow symbol.
• If you duplicate a layer that includes one of the boxes in the middle of the story, all of the text in that box, as well as the text in the linked boxes that complete the story, is duplicated. The middle box displays on the duplicated layer and displays an overflow symbol. None of the text from any preceding boxes in the story is copied onto the duplicate layer.
• If you duplicate the layer that contains only the last box in a story, only the text in that last box, and none of the text from any preceding boxes in the story, is copied to the duplicate layer.
