 +====== Monitoring Windows ======
  
 +''screen'' can monitor your windows, either for silence or activity, notifying
 +when the condition occurs.  This is useful for all sorts of things, including
 +waiting for a lengthy compile to finish or watching log files.
 +
 +===== Basics =====
 +
 +Use ''[[commands:monitor|C-a M]]'' to start monitoring a window for activity.  ''[[commands:silence|C-a _]]''
 +monitors for 30 seconds of silence.  Using the appropriate key combination
 +a second time will turn off monitoring.
 +
 +===== Extras =====
 +
 +There are a couple of configuration commands that can be used to tweak the
 +monitoring settings.  ''[[commands:silencewait]]'' will change the number of seconds of
 +silence that will trigger the monitor.  ''[[commands:activity]]'' sets the message that
 +screen shows when a monitored window has activity.  [//There doesn't seem
 +to be a way to set the silence message.  Is this correct?  <PMG>//]  The message
 +uses the standard [[man:string escapes]], as well as replacing '^G' with an
 +ASCII BEL (so the terminal will beep).
 +
 +Setting the timout for silence monitoring affects all windows.  There's no
 +way to have different timeouts for different windows.
 +
 +===== Keybindings =====
 +
 +  * ''[[commands:monitor|C-a M]]'' - Start/stop monitoring window for activity.
 +  * ''[[commands:silence|C-a _]]'' - Start/stop monitoring window for inactivity.
 +
 +===== Commands =====
 +
 +  * ''[[commands:activity]]'' - Set message displayed by screen when a monitored window shows activity.
 +  * ''[[commands:defmonitor]]'' - Set the default monitoring status for new windows.
 +  * ''[[commands:defsilence]]'' - Set the default silence monitoring status for new windows.
 +  * ''[[commands:monitor]]'' - Set the monitoring status for the current window.
 +  * ''[[commands:silence]]'' - Set the silence monitoring status for the current window.
 +  * ''[[commands:silencewait]]'' - Set the silence timeout for all windows.
 +
 +===== Examples =====
 +
 +Change the activity message to include a timestamp and window title, as
 +well as beep.  In practice it will read something like "12:37 activity ->
 +7$ zsh":
 +
 +<code>activity "%c activity -> %n%f %t^G"</code>
