flash actionscript: noroc

some sites (non-flash) have this button-colour mark-up. i mean, that when you
click a certain button, on the next page it becomes coloured different from the
other buttons for the user to be able to now o whitch page he is navigating at
that certain moment.

i would like to achieve the same effect with a flash header and not using
frames.

here is a site so you would be able to understand better:
