I have an GUI application written in PyGTK and need to read key-press/release events from application menu. 

For example, when pressing shift key and click on menu item, do something else, then ordinary. gtk.Menu implement this signals and it works very well for the application, until Unity move the menu to panel - no more events from menu. I'm not willing to redesign GUI because of Unity, hope there's a better way. Thanx in advance for any hint.
