Hi,

I had to tweak the expression a little to make it work correctly. Lloyd,
the expression you gave me has one flaw : Opacity turns off as soon as the
next marker is closer to the current marker, no matter its duration.

This seemed to work :

  n = 0;

if (marker.numKeys > 0){
  n = marker.nearestKey(time).index;
  if (marker.key(n).time > time){
    n--;
  }
}

if (n == 0){
  0;
} else {
  (time >= marker.key(n).time && time <=  (marker.key(n).time +
marker.key(n).duration))?100:0;
}


Thanks,


Salvador
