Callback functions allow us to centralize all of our code in a keyframe.

The old way to respond to events was to attach actions directly to an instance:
on(press) {this._x=100;}

Now, (with callback functions) you refer to an instance from the keyframe and respond to any event:
myButton.onPress=function(){this._x=100;}
or:
instanceName.eventName=someFunction

Now you won't have to click on all of your instances to find the piece of code you want to edit. You just click on the keyframe that holds all of your code and edit it there. More upfront planning but way easier debugging and modification.

Callback functions can be added to any object that can be referred to with an instance name.

Hope that helps, I'm trying to give some back to the Kirupa forums.

In your xml put

<caption><![CDATA[<a href="http://www.kirupa.com"><u>Kresge</u></a>]]></caption>
in flash enable the text field for html, lest say you want to show the value of myArray[i]

your_txtfield.html =true;
your_txtfield.htmlText =myArray[i];
will show as Kresge and link to kirupa.com:)
