This provides a way to turn keyboard short-cuts on and off. For windows that you create with the window.open() method, you can control this with the feature list that you pass to the open() method.
Pass a true value to activate the hot keys and a false value to deactivate them.
Your script will need to be granted the UniversalBrowserWrite privilege to allow it to call this method in Netscape Navigator.
Beware of the spelling, the word 'keys' is not capitalized inside this function name.
