screen: Caption

 
 9.6 Caption
 ===========
 
  -- Command: caption 'always'|'splitonly' [string]
  -- Command: caption 'string' [string]
      (none)
      This command controls the display of the window captions.  Normally
      a caption is only used if more than one window is shown on the
      display (split screen mode).  But if the type is set to 'always',
      'screen' shows a caption even if only one window is displayed.  The
      default is 'splitonly'.
 
      The second form changes the text used for the caption.  You can use
      all string escapes (SeeString Escapes).  'Screen' uses a
      default of '%3n %t'.
 
      You can mix both forms by providing the string as an additional
      argument.
