Creates a copy of the selection. After clicking the menu item or pressing the keyboard shortcut, move the mouse to move the copy to the desired location and press LMB or Return to confirm. Alternatively, press RMB or Esc to leave the copy at the same location as the original. (The copy will still be selected, so it can still be easily moved out of the way afterwards.)
