According to that Cheat Chart it's number or letter plus * BUT according to BIAB it's the letter/number + dim.
According to the numbers system you needn't add it as, if the key is set & the numeral/number added, it should KNOW it's dim.

Nice cheat chart.
Like so may it has far too much going on but it'd still be very handy.

The numerals/number system is a cool tool but it's an "in the know" tool because one has to know each key for it.

"Anyone at any musical theory level or anyone with no musical theory knowledge at all or even those with false or incorrect belief in what they think is musical theory can with access to and using the BIAB program can 'see' and 'hear' for themselves with no influence or direction from anyone, complex chords, progressions, dynamics and rhythms using Nashville Numbers."

OR any other way.

Music theory isn't really theory: it's a grammar for communicating information from a culturally, (let's be honest most theory is based on the tonalities of a couple of hundred years back), language.

The dabbling player/writer, with a limited musical vocabulary would, in all likelihood, enter the chord they play/hear. Using numbers/numerals would create some problems for borrowed chords, modulation etc. - things that BIAB can do but not quite as easily as entering the chords.

It's really hard for the musically educated & adept to get into the shoes of a novice or dabbler. That's why many, MANY music "teachers", Maths "teachers" and such have trouble communicating the thing they love so much.
