I checked on what you suggested and realized that this behaviour is only occuring when using the freenx client in windows. When i switch to the actual FC6 box and actual X session, the SHIFT+ALT+> works just fine, my mistake for not checking this.
So, this must be related to somthing freenx is doing. I don't see any setting to control keyboard mapping. ESC+ALT actually brings up the kill session dialog for freenx. Thanks for the suggestion, it has helped me barrow it down. I will try searching the freenx site.
