???
I was thinking of scripts which (might) put "\transpose c d" into
various possible fields. Oh, and one script, OpenOctaveUp that is
already in there (it is opening a block to be transposed in the LilyPond
output - this is one that I use if the range of a piece is mostly ok but
some bits need octave transposition).
Needs thought for how to make this easy for folk to understand.

As well,
I meant to say something about the conventions for variable naming:

All globals should be prefixed by the command name::
for a group of commands with an init, by the menu name.
The uppper/lower case of the variable name after the :: indicates
public/private, so
Transpose::Interval is public (would be Transpose::interval if it was
private)
