Monitoring keyboard by an application in System Tray

[Sundaram <legends2k yahoo com>]

Hi all,
I want to know the procedure to monitor the keyboard for a particular key combination, by an application that 
sits on the System Tray. Can it be done thru' registering for signalling /callback? How is this possible in a 
GTK+ application?

Thanks!

Best Regards,
Sundar
