Make F1 key customized (was Newb help)

[#1]

In JMP 16 (Windows) , I removed the F1 hotkey from Help and set up as a new function using Custom Menus and Toolbars.
I did the same in JMP 17 standard, and yet when I hit F1, I still get the Help browser link.  Is there another place that F1 is set up that I am missing?  Or is it hardcoded?

To my knowledge there are some shortcuts which cannot be modified and it seems like F1 is one of them (I have had to workaround quite a few of those "hard-coded ones"). I'm not sure if all of these are something which you cannot change JMP documentation (Keyboard Shortcuts).
