  10 Hi all,
  11
  12 I have extend Mats' patches to allow accidental transposition:
  13         \keysignature bes es fis
  14                 = \transpose c' d =>>
  15         \keysignature gis
  16
  17 As you can see in output =  the example file "test.ly" there are a few problems left:
  18 - key undo (already in the Todo)
  19 - "wrong" transposition: e.g. \transpose c' d of fis-major = gis-major (better as-major?).
  20         The solution gis=as etc. would concern both note and key transposistion
  21

  24 - Note that transpose eses of fis-major = as-major
  25 - Note also that key signatures specified with \property keySignature
  26   are not transposed!
