I can never remember all that music theory, so I create little notes.  Yes,
transposers help but don't do everything I need.  What key had 3 flats?  Was
the order of sharps B, E, A, D, or ??  This brief key chart that has helped me,
and I keep it (credit card sized) in my wallet.  I hope you find it as useful.

How do you read it?  Examples:
Key of G (4th row) has 1 sharp (3rd row) and that sharp is F# (5th row).
Key of A (4th row) has 3 sharps (3rd row): F#, C# and G# (5th row).
    5th row gives the LAST sharp.
Key of A flat (A- in 2nd row) has 4 flats (3rd row): B-, E-, A-, D- (1st row).
    1st row gives the LAST flat.  Lacking a flat symbol, ` - ' was used.
