  Syntax:  BOX COPY

  Copies the selected box to buffer $PASTE or the clipboard.

  This command copies the currently selected box to the default
  location (the DECwindows clipboard or paste buffer).  The diagonally
  opposite corners of the box are given by the beginning and end
  positions of the current selection.
