256 Moving and Cloning Selections
Sounds easy enough, right? When you move the selection, however, be warned that the area where the selection used to reside is now filled with the background color, as shown in Figure 3-9. This is provided, of course, that you are moving both the selection outline and the image pixels. You can move just the selection outline (without the pixels), as I explain in an upcoming sec-tion. Also note that if you are moving a selection on a layer, you are left with transparent pixels. When you use the Move tool, your cursor icon changes to a pair of scissors, letting you know that you are cutting out the selection.
