On my MacBook, "Fn + Command + b" seems not to be working with DoubleCommand.

When I press keys "Fn + Command", then hit a key "b"(Key code  11), debugging log says I hit the key "Command"(Key code 55) like:

  Filtering: In.... keyCode: 55:37, keyDown: 0, keyBits: 0, repeat -1
  Filtering: Out... keyCode: 55:37
  <snip>
  Filtering: In.... keyCode: 55:37, keyDown: 1, keyBits: 0, repeat -1
  Filtering: Out... keyCode: 55:37

All keys but the key "b" seems to be working fine with "Fn + Command".

Thanks,
