   2 Hi all,
   3
   4 I have extend Mats' patches to allow accidental transposition:
   5         \keysignature bes es fis;
   6                 = \transpose d =>
   7         \keysignature gis;
   8
   9 As you can see in output the example file "test.ly" there are a few problems left:
  10 - key undo (already in the Todo)
  11 - "wrong" transposition: e.g. \transpose d of fis-major = gis-major (better as-major?).
  12         The solution gis=as etc. would concern both note and key transposistion
