In Elements 11 each time I copy a shape the pasted copy appears in a new layer. I would like to have the pasted copy stay in the same layer as the original shape. How do?
When you paste, it's always going to come in on a new layer, just merge them back together again afterwards, or use the shape selection tool to alt/option drag a shape with the add to shape button turned on. The shape selection tool is the gray arrow in the list of shape tools in the tool options.
