    etmctrl.sh [-v] (-a|-c|-R|<argument>)

  -a    Activate the etm window by switching to its desktop and raising it.
  -c    Close the etm window gracefully.
  -R    Move the etm window to the current desktop and activate it.

and the format for <argument> is:

   (remove|add|toggle),<PROP1>[,<PROP2>]
