When interacting with a Flash movie embedded in the browser,
it doesn't appear that you can easily use Javascript to intercept
the key presses. Based on the tests I've done, it seems that the
Flash movie receives the key presses and then passes them on to the
browser, rather than the other way round as one might expect.
I think the best (and possibly only) way to prevent default
browser functionality from triggering would be to create a little
movie in Flash that prevents key presses from being passed on to
the browser, then bring that movie in as an animation on the slide
where you want the key to be blocked.
You might also want to submit a feature request to Adobe to
add the ability to indicate whether a Shortcut key gets passed on
to the browser when pressed.
