The command acts in a similar way
to the 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” 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” command places
the data from the Clipboard into the center of the canvas, as the
“Paste” command does.
