screen: Monitor

 
 10.6 Monitoring
 ===============
 
  -- Command: activity message
      (none)
      When any activity occurs in a background window that is being
      monitored, 'screen' displays a notification in the message line.
      The notification message can be redefined by means of the
      'activity' command.  Each occurrence of '%' in MESSAGE is replaced
      by the number of the window in which activity has occurred, and
      each occurrence of '^G' is replaced by the definition for bell in
      your termcap (usually an audible bell).  The default message is
 
           'Activity in window %n'
 
      Note that monitoring is off for all windows by default, but can be
      altered by use of the 'monitor' command ('C-a M').
 
  -- Command: defmonitor state
      (none)
      Same as the 'monitor' command except that the default setting for
      new windows is changed.  Initial setting is 'off'.
 
  -- Command: monitor [state]
      ('C-a M')
      Toggles monitoring of the current window.  When monitoring is
      turned on and the affected window is switched into the background,
      the activity notification message will be displayed in the status
      line at the first sign of output, and the window will also be
      marked with an '@' in the window-status display (SeeWindows).
      Monitoring defaults to 'off' for all windows.
 
  -- Command: silence [STATE|SEC]
      ('C-a _')
      Toggles silence monitoring of windows.  When silence is turned on
      and an affected window is switched into the background, you will
      receive the silence notification message in the status line after a
      specified period of inactivity (silence).  The default timeout can
      be changed with the 'silencewait' command or by specifying a number
      of seconds instead of 'on' or 'off'.  Silence is initially off for
      all windows.
 
  -- Command: defsilence state
      (none)
      Same as the 'silence' command except that the default setting for
      new windows is changed.  Initial setting is 'off'.
 
  -- Command: silencewait SECONDS
      (none)
      Define the time that all windows monitored for silence should wait
      before displaying a message.  Default is 30 seconds.
