The Paste Into Selection command acts in a similar way to the Paste command. The primary difference becomes apparent if there is a selection within the canvas. Unlike the “Paste” command, which simply centers the pasted image data over the selection and replaces the selection with its own, “Paste Into Selection” clips the pasted image data by the existing selection. The new selection can be moved as usual, but it is always clipped by the original selection area.

If no selection exists, the “Paste Into Selection” command places the data from the Clipboard into the center of the canvas, as the “Paste” command does.
