Finding Texts in Flash

Hi,
I am making a presentation (to work on a CD) that needs to have a search for texts. In this presentation there are lots of texts and I need to give the user the opportunity to search word.
I would like to have a text finder that goes to the word I am looking for, then, clicking again its to the next occurrence of this word.
Could any one help me, please.
Thanks in advance.
