I have a question how to disable ESC key in full screen. I mean that when i am in full screen mode I don’t want to leave it by pressing ESC but only by pressing Ctrl+Shift+J.
The purpose is to build full screen application without menu, toolbars and stuff like this. I don’t want to let user get out from full screen mode when he press ESC.
ESC is to ordinary key. Ctrl+Shift+J is not 
Thank you in advance for any hint.
