The copy becomes a floating selection, which seems to hover above the main image. You can move a floating selection, or you can select the Transform tool to scale or rotate the floating selection.

• Click outside the floating selection to deselect it. The selection’s content is pasted into the image, replacing the pixels that were below it.

• Click in the floating selection with either the Marquee or Transform tool and Alt-drag (Windows) or Option-drag (Mac OS) to make another copy. Once copied, the original floating selection is deselected and replaces the pixels that were below it.

  Pressing Control+Shift+T (Windows) or Command+Shift+T (Mac OS) duplicates your last duplicating move. This is an easy way to clone content multiple times.
