Using the Clone Source palette (Window > Clone Source), you can set up to five different sample sources for the Clone Stamp tools or Healing Brush tools. You can display an overlay of your sample source to help you clone the source in a specific location. You can also scale or rotate the sample source to clone the sample at a specific size and orientation.

(Photoshop Extended) For timeline-based animations, the Clone Source palette also has options for specifying the frame relationship between the sample source video/animation frame and the target video/animation frame. See also Cloning content in video and animation frames (Photoshop Extended)
