To remove a drawn Marquee area, do one of the following:
•Press Esc.
•Click with the right mouse button or Ctrl-click (MacOS), and choose the Remove Marquee command in the appearing context menu.
•Begin drawing a new Marquee.
•Double-click in the window outside the marquee area with the Marquee tool selected.
If you have explicitly selected further elements within the Marquee, pressing Esc will deselect these elements in reverse order, and finally remove the Marquee.
If you choose another tool, the Marquee area will not be removed, in order to save the recent Marquee area for further use.
