      (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 (SeeString 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'.
