Exit Button within an offline .exe

Here i am again,

Now i published an exe file, but many peope don't know they can quit it (because it is fullscreen) with the ESC button on your keyboard. Now i want to put a 'QUIT' button inside the project, with a script to close the offline .exe
I know you can insert a button with many actions like, go to latest slide, but nothing like, close this slide(exe).

Is this possible, i think yes with some javascript ? but what is the right text to quit an offline exe file? (i know the script for closing webpage but that don't work within the offline exe file.

Grtz.
Bill
