ONE WINDOW
  Restores a single, large window when the EVE main window is split into two
  or more windows.
  Steps:
     1.  Put the cursor anywhere in the window you want to keep
         (see help on NEXT WINDOW or PREVIOUS WINDOW command).
     2.  Use the ONE WINDOW command.
  Example:
     If you have two windows (as at the left below), using ONE WINDOW makes
     the current window fill the available space (as at the right):
        Before                 After
        +---------------+      +---------------+
        |   ALPHA.TXT   |      |[]             |  The cursor ([]) stays in
        |               |      |               |  the same position in the
        |---------------|      |               |  buffer you are editing
        |[]             |      |   BETA.TXT    |  (in this case, BETA.TXT).
        |    BETA.TXT   |      |               |
        +---------------+      +---------------+
  Usage notes:
  o  Deleting a window does not delete the buffer in that window. (To delete
     a buffer, use the DELETE BUFFER command.)
  o  To delete the current window, keeping the other window or windows, use
     DELETE WINDOW.
  o  For more information about using multiple windows in EVE, see help on
     Windows.
