* by clicking on "Click here and I will point it out" at the end of the first paragraph.<br>
* <pre><code>
var animator = new YAHOO.ext.Animator();
var cursor = new YAHOO.ext.Actor('cursor-img', animator);
var click = new YAHOO.ext.Actor('click-img', animator);
var resize = new YAHOO.ext.Actor('resize-img', animator);
// start capturing
animator.startCapture();
// these animations will be run in sequence
cursor.show();
cursor.moveTo(500,400);
cursor.moveTo(20, getEl('navbar').getY()+10, true, .75);
click.show();
click.alignTo(cursor, 'tl', [-4, -4]);
// Add an async function call, pass callback to argument 1
animator.addAsyncCall(Blog.navbar.undockDelegate, 1);
// pause .5 seconds
animator.pause(.5);
// again, these animations will be run in sequence
click.hide(true, .7);

// play the captured animation sequences, call myCallback when done
