May I humbly make a suggestion for the worksheet KEY menu?

C - Am - 0# 0b
G - Em - 1#
D - Bm - 2#
A - F#m - 3#
E - C#m - 4#
B - G#m - 5#
F# - D#m - 6#
C# - A#m - 7#
Cb - Abm -7b
Gb -Ebm - 6b
Db -Bbm - 5b
Ab -Fm - 4b
Eb -Cm - 3b
Bb -Gm - 2b
F - Dm - 1b

This covers all the practical keys you'll ever see. There are only 15 choices.
As for the others, if one wants to compose something NO ONE can read,
well, have at it ! ! !
