// Slides a MovieClip to _x = 200 after 10 seconds are elapsed (AS2)
Tweener.addTween(myMovieClip, {_x:200, time:1, delay:10});
// Fades a MovieClip in, then out (AS2)
Tweener.addTween(myMovieClip, {_alpha:100, time:1});
Tweener.addTween(myMovieClip, {_alpha:0, time:1, delay:1});
// Uses an empty tweening to trace "hey!" after 5 seconds
Tweener.addTween(this, {delay:5, onComplete:function() { trace("hey!"); }});
// Sends a MovieClip to _x = 200 *immediately* after 10 seconds are elapsed (AS2)
Tweener.addTween(myMovieClip, {_x:200, delay:10});
