Flipping or Rotating a Layer

The purpose of flipping or rotating a layer can be either to change the position of the objects on the layer or to vary the effect of a gradient or pattern layer. The Image, Rotate command has a submenu section for such operations performed on entire layers.

Click the layer name in the Layers palette to make it the active, or current, layer.

Optionally, Ctrl-click layer names in the Layers palette to select any other layers that must be included in the operation.

Choose Image, Rotate and choose from the second group of submenu commands, such as Flip Layer Vertical.
