Your change would cause all applications (not just whiptail) to react to ESC. A better way would be to add ESC as a hotkey in whiptail. It should probably be limited to dialogs that have the cancel button, otherwise I suspect it might lead to unexpected behavior. Another option is to fix the man page to not mention the escape key. |

I'm not even sure if you accept pull requests, since don't seem to be any.
I couldn't get the ESCAPE key to exit whiptail forms, so I found the omission and added two lines of code.
