Edit layer with code

Question

Hi all. I'm trying to create snippet/script that is able to edit the selected layer on the timeline.
More specifically I want to add an instance name to a certain movie clip on the selected layer.

I.e. if the user select a layer and execute the script then it should add the same instance name to each key frame on that layer. Hope it makes sense.

I'm not sure if it is event possible to create something like this.
I'm currently staring to learn ActionScript 3.0, so please excuse me for the dumb question.
Any help or resources/guides will be much appreciated.
Thank you.

Save this script as a command and execute it via "Commands" menu.

(function(){
			
	var myInstanceName = prompt( "Instance name:" );
	if( ! myInstanceName ) return;
	

	var tml = fl.getDocumentDOM().getTimeline();
	var myLayer = tml.layers[ tml.currentLayer ];
	var i, myFrame, j, myElement, myReport = {frameCount:0, elementCount:0};

	// Add 'button' to this array if you want to name the button instances as well
	var myTypes = [ "movie clip" ];
	
	
	for( i = 0; i < myLayer.frames.length; i++ ){
		myFrame = myLayer.frames[ i ];
		
		// Skip non-keyframes
		if( myFrame.startFrame != i ) continue;
		
		myReport.frameCount ++;
		
		for( j = 0; j < myFrame.elements.length; j++ ){
			
			myElement = myFrame.elements[ j ];
			
			if( myTypes.indexOf( myElement.symbolType ) > -1 ){
				myElement.name = myInstanceName;
				myReport.elementCount ++;
			}
		}
	}
	
	fl.outputPanel.clear();
	fl.trace( "Layer: " + myLayer.name );
	fl.trace( "Frames: " + myReport.frameCount );
	fl.trace( "Instances: " + myReport.elementCount );
})();

layers don't exist in swf files, so are you asking about jsfl code to edit your fla?
