How do I make actionscript run under certain condition?

Question

package {
    import flash.display.Sprite;
    import flash.events.*;
    import flash.net.FileReference;
    import flash.net.FileReferenceList;

    public class FileReferenceListExample extends Sprite {
        public static var LIST_COMPLETE:String = "listComplete";
        public function FileReferenceListExample() {
            initiateFileUpload();
        }

        private function initiateFileUpload():void {
            var fileRef:CustomFileReferenceList = new CustomFileReferenceList();
            fileRef.addEventListener(FileReferenceListExample.LIST_COMPLETE, listCompleteHandler);
            fileRef.browse(fileRef.getTypes());
        }

        private function listCompleteHandler(event:Event):void {
            trace("listCompleteHandler");
        }
    }
}

Code like the above will get executed as soon as loaded,how can I make it run under certain condition?

Pretty much this in this answer:

function keyEvent(code:String):void {
    // do something with the "code" parameter, that looks like "alt+ctrl+D", may use .split('+'), etc
}

Answer 1

you may want to register KeyboardEvent listeners to the stage.
