Found another snag with this. Using Fn activates the numeric keypad
emulation of the keyboard, effectively blocking commands p,m,o.
Unfortunately can't use F12 itself here as that is mapped as a button.
Code below uses Alt-F11, but I'm not sure if that is specific enough
as it could be used by normal applications. Any sugestion for a better
key combination to use?
