controlling a flash "movie" through html?

first off, thanks for looking!

im in the process of making a portfolio website.
i have the main page done using html & css and it's looking grand.
anyway i have a a flash movie (lets say main frame) which loads all the other movies (various content) and was wondering if it was possible to have the flash movie listen for specific button clicks in the html document.

ie:
user clicks the cv button (with the alt tag "CV") and the flash movie goes to the appropriate keyframe in the "main frame" which loads the CV content.

so ideally the flash movie would listen for CV PORTFOLIO & CONTACT alt tags and go to the relavent frames in the "main frame".
anyone know how to do this?
