[MlMt] custom key to view as html

[Randy Bush]

i generally prefer text rather than html.  but sometimes i want to see a
message as html, and without my claws leaving the keyboard.  so i tried
to figure out how to map a key to View/MessageBodyParts/HTML.  clearly,
it goes in, e.g.

    ~/Library/Application Support/MailMate/Resources/KeyBindings/Special.plist

but i can not find the action name, and can not find how to find the
\@U.... for keys.

clue bat, please.
