Fix Corners  - Copy Rectangle

The next step is to "copy" the rectangle.  To do this, use the keyboard shortcut for "copy", which is "CTRL+C".  So hold the "CTRL" key down, and while holding it down, press the "C" key down firmly, and then let them both up.  This copies the contents of the dotted rectangle to the Clipboard.  Now the next steps must be followed exactly.
