The original keyboard for PET (Business 8032) cannot open the menu in BMPET because it lacks function keys (e.g., F12)

I have successfully set up BMPET on a Raspberry Pi 3. I am using the original keyboard with a USB adapter. The problem is that there are no function keys or a Commodore key, so I cannot open the menu with F12 or C= + F7, as these keys are missing. Is there another way to open the menu?

With no menu, I have no floppy access on any other settings.

I created a switch using some GPIO Ports to open the menu, however this is really a workaround, a proper way from keyboard would be great. Thanks.
