I was also thinking about B - Bulb but that went a bit to far
M is quite often use and refer mostly to Manual or should I make it M-Mode but that would mean I would also need to dat that with Tv Av and TAv

Yes it means function also adding it just to make it complete as far as it goes.

MUFC might be for another list but not this one sorry
It will probable go into the internet abbreviations and acronyms
