  -- Command: rendition bell | monitor | silence | so ATTR [COLOR]
      (none)
      Change the way screen renders the titles of windows that have
      monitor or bell flags set in caption or hardstatus or windowlist.
      See the chapter about string escapes (⇒String Escapes) for
      the syntax of the modifiers.  The default for monitor is currently
      '=b' (bold, active colors), for bell '=ub' (underline, bold and
      active colors), and for silence '=u'.
