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 (⇒String Escapes).  'Screen' uses a
      default of '%3n %t'.
 
      You can mix both forms by providing the string as an additional
      argument.
