Go to next label or previous label

Question

Is there an action in Animate to play next label or stop at  previous label?
Thanks for any support.

Hi, guys.
It's not a formal , but there is also such a way.
The label information, can be accessed in the "Default Timeline" via.
console.log(sym.timelines['Default Timeline'].labels);
So, use this, We can extend the Edge-Symbol. like this.
//document.compositionReady
//get label index for the time
Symbol.prototype.getLabelID = function(time){
  time = time||this.getPosition();
  time = Math.max(time,1);
  //mapping the label name & time
  var ex = this.ex = this.ex||{};
  if(!ex.labels){
    ex.labels = [{time:0,name:'start'}];
    if(this.timelines['Default Timeline'].labels){
      $.each(
        this.timelines['Default Timeline'].labels,
        function(key,val){ex.labels.push({time:val,name:key});}
    //sort by time
    ex.labels.sort(function(a,b){return (a.time<b.time)?-1:(a.time>b.time)?1:0});
  //serch the label index
  for(var i=1;i<ex.labels.length;i++){
    if(time<ex.labels[i].time)break;
  return i-1;
Symbol.prototype.getNextLabelTime= function(time){
  var id =this.getLabelID(time);
  var labels = this.ex.labels;
  //return labels[Math.min(++id,labels.length-1)].time;
  return labels[++id%labels.length].time; // case loop
Symbol.prototype.getPrevLabelTime= function(time){
  var id =this.getLabelID(time);
  var labels = this.ex.labels;
  //return labels[Math.max(--id,0)].time;
  return labels[(--id+labels.length)%labels.length].time; // case loop
Symbol.prototype.nextLabel=function(play){
  var func =(play)?this.play:this.stop;
  func.call(this,this.getNextLabelTime());
Symbol.prototype.prevLabel=function(play){
  var func =(play)?this.play:this.stop;
  func.call(this,this.getPrevLabelTime());
In this. We can use prevLabel/nextLabel method.
//move to next label
sym.nextLabel();
sym.getSymbol("Symbol_1").nextLabel();
//move to prev label and play
sym.prevLabel(true);
etc..
Because it extends the Edge-Symbol on its own, It's not the way "well-behaved".
If you are interested, try .
thanks.
