Open a different flash in Fullscreen web browser

Hi,
I found tons of script for full screen action (Stage[“displayState”] = “fullscreen”;). But all it does is to make full screen the running flash file, how can I call deferent flash file to be loaded on clicking a button.
Like in following website if you click on
“Explore all our kitchens now “ , it opens a different flash file in full screen mode.
And when u press Esc, it closes and comes back to original link page.
