Ctrl+W and Alt+F4 can be used to close the IE browser, but I am looking to disable this default action. While I have found a way to handle the Ctrl+W command, I am struggling with disabling the Alt+F4 event. It seems that other Alt+Key events like Alt+Enter, Alt+Right Arrow, and Alt+Left Arrow cannot have their default actions disabled. Is there a way to disable the Alt+Key event in the IE browser?
