Opening static text box from dynamic text box

programming flash
1

In my flash site, I have a scrolling dynamic text box. In this text box, I would like to provide links that either

  1. open another dynamic text box in the same movie (prefered)
  2. open a pop-up window

If I use a button this is no problem, I just follow some of the tutorials, but trying to get the URL Link to display this behavior has escaped me. Is it even possible? :h:

The idea is that as a person reads the text, they can click on select words and an explanation will ‘pop-up’ regarding the word in question.

Thanks much in advance.
