Is there a reason that these codes are not documented in the module documentation?

Is there a reason that the MicroSoft codes are not used?

Is there a reason that the symbolic names are not the same as the MicroSoft symbolic names?

Why do keys such as 'A' not work?

Would it not have been simpler to use and document (and possibly also to write the code) to pass an integer value straight through, convert letters to the uppercase equivelent ordinal code and possibly do some symbolic conversion as icing?

Why is the sample code mentioned in the documentation not provided?
