Set Pending Delete
  Determines whether you can erase a selection by using DELETE (the <X] key)
  or typing new text.
  Usage notes:
  o  By default, pending delete is disabled. Thus, whether there is a
     selection or not, DELETE erases the character left of the cursor, and
     typing new text puts characters at the current position.
  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.
  o  To insert the text you erased with a pending delete operation, use
     RESTORE SELECTION or RESTORE BOX SELECTION.
  o  SELECT ALL (or M1CLICK5) temporarily disables pending delete to prevent
     your accidentally erasing the entire buffer.
