You can type the Insert key by typing Fn+Delete on the official Raspberry Pi Keyboard. I miss these keys: Pause, Super R (Right Windows key), Menu, Enter (on the num pad). Shift+F10 is an alternative to Menu, but doesn't send the Menu scan code. I think there should be combinations with Fn that makes it possible to generate all scan codes on a pc105 keyboard plus multimedia keys.
It would be a wish that the next version of the official Raspberry Pi Keyboard could generate all scan codes for pc105 even if it is the US version (i.e. pc104), because then I think Fn+Z should generate the key left of Z on a pc105 keyboard. Fn+B could be Pause key ─ it cannot be Fn+P because that's already - (minus) on the numeric keypad. Fn by itself doesn't send a scan code. It would also be good if multimedia keys were supported using e.g. Fn+F3 to Fn+F9.
