Delete one or more states from the Undo History palette

 Do one of the following:
  • To delete a state, click the name of the state, and choose Delete from the Undo History palette menu. States following the one you selected are also deleted.

  • To delete the list of states from the Undo History palette, without changing the image, choose Clear Undo History from the palette menu or choose Edit > Clear > Undo History. Clearing is useful for freeing up memory, especially if you get an alert that Photoshop Elements is low on memory.

    Note: Clearing the Undo History palette cannot be undone.
