Hi Hemant,
In essence, to redefine or modify a NewtonScript function, you redefine the
parent frame using its _proto, and tacking on your new or replacement function.
The RotateBook page has source code that shows how this is done to patch the
Newton's internal book reader. Applies to any other app though, built-in or
third-party.
