OK, but then where in Key Mappings do I find it so I can disable it?
It is very confusing for me not having used these be

Yes, now that you mention it...

I would like to be able to communicate on the I2C bus from my
FPC/Lazarus programs on Raspberry Pi.
There are at least two cases:
1) Reading devices like RTC chips and other sensors.
2) Reading/writing data stored in EEPROM chips
Since the Raspbian system is a Debian Linux derivative I am hoping

I am wondering how exactly I should package the program I am

It is an Arm binary for RPi3 or Rpi4 type units running Raspbian
Buster. So I could stuff the binary into /usr/bin I suppose, but it
