Apple Color OneScanner 600/27 - Manual (Page 82)

As you extend the painting, the rest of the cloned image appears—or as much
of it as you want to paint.
Tip: For a more natural appearance, reposition the reference point from time
to time. To do this, press the Option key and click the new spot you want to
clone.
Smudging
To smudge colors and lines into other colors and lines:
1 Select the smudge tool.
2 Drag through colors and lines.
The tool takes colors with it as you drag, much the same way your fingers
smear wet paint when you paint with your fingers.
