Reverting to an earlier image state
As you create or edit an image, you can revert to its last-saved version to remove all the changes you made since you saved the image. If you want to remove only some changes, you can restore specific image areas to the way they look in the last-saved version of the image.
You can also create a checkpoint to save the current image temporarily, so that later you can return the image to that state if necessary.
You can also create a workspace that lets you save automatically using a checkpoint. For more information, see “To specify auto-save settings.”
