Set Box Select

  Determines the type of selections for cutting, pasting, and other edits.
  "Box selections" let you edit a rectangular area, rather than a linear
  range. For example, you can select, cut, and paste columns of text, such
  as in editing a table.

  Usage notes:

  o  By default, box selection is disabled, so you can select and edit
     standard, linear ranges. To edit boxes, use BOX commands.

  o  Enabling box selection makes commands (or defined keys or menu items)
     for editing linear ranges work like like BOX commands. For example,
     SELECT, REMOVE, and INSERT HERE are then the same as BOX SELECT, BOX
     CUT, and BOX PASTE respectively. See help on Ranges And Boxes.

  o  Typically you enable box selection to make it easier to edit tables or
     column-aligned text without having to redefine keys for selecting,
     cutting, and pasting. In effect, the setting redefines the keys for
     you.

  o  Enabling box selection also affects editing a found range. For example,
     COPY, FILL, REMOVE, or UPPERCASE uses the start and end of the found
     range as the diagonally opposite corners of a box.

  o  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.
