Copy

  Copies text within the selected range and moves it into a designated
  buffer (by default, the $PASTE buffer or the clipboard in DECwindows mode).
  The selected range is the text between the select marker and the current
  cursor position.  If no select marker has been set, and the cursor is
  positioned on the current search string, then that string is moved to the
  buffer.

  Command Equivalent:

          CUT/NOERASE
