In Flex, how to use command-shortcuts in the browser?

I tried catching the command key shortcuts using the keyDown event and checking for KeyboardEvent.ctrlKey, but the browser(Safari) seemed to have intercepted all those key events because the shortcuts I am trying to use coincides with the safari ones. Is there anyway to override this behavior?

• Unfortunately there's no way to mitigate the native browser handling of keystrokes directly from flash. You could create an adobe AIR app if thats even an option or check out that comment posted on your question to try doing it with javascript.
