SET BOX NOSELECT    (default)
  Disables box-style selection, cutting, and pasting, so that SELECT,
  REMOVE, INSERT HERE, and other commands or keys use standard, linear
  ranges.
  Usage notes:
  o  To select a box, use BOX SELECT. To copy or cut a box, use BOX COPY or
     BOX CUT.
  o  If you enable box selection, SELECT, REMOVE, STORE TEXT, and INSERT
     HERE are the same as BOX SELECT, BOX CUT, BOX COPY and BOX PASTE---for
     example, any key defined as SELECT then works like BOX SELECT without
     having to be redefined.
  o  SET BOX NOSELECT applies in all buffers. To save your setting for
     future editing sessions, use SAVE ATTRIBUTES to create a section file
     or to create or update a command file---see help on Attributes.
  o  On DECwindows, you can toggle the setting as follows:
        1.  Choose Global Attributes from the Customize menu.
        2.  Click M1 on Set Box Select in the dialog box.
