// Edit this list to choose what sounds to play when, depending on which icons
// are lit in the status panel. The order in which the lines below is given is
// used to signify which sound wins when several icons are lit; the first sound
// that is not commented out and is lit, will be played. To play local files on
// your hard disk, use URLs such as file:///C|/Windows/Media/notify.wav
// In case you (like these example settings) leave out some icons and want a
// "catch-all" sound for those not explicitly mentioned, keep the "any" line.
