Changing keyboard bindings in Outlook 2007 editor?

[Catweazle]

Is there any way to change the keyboard bindings in the Outlook 2007 email
editor?

With Outlook 2003 I've been using a VBA package that provides Emacs-style
key bindings in Word, available at http://www.rath.ca/Misc/VBacs/

These no longer work in the Outlook 2007 editor, which I understand
is based on Word 2007 but implemented through some dll "stub" (although I
do also have the "full" Word 2007 installed).

After running filemon it seems that the Outlook 2007 editor is no longer
loading any .dot files from \Documents and
Settings\<user>\ApplicationData\Microsoft\Word\STARTUP .

Is there any way to get the Outlook editor to load these .dot files?

Alternatively, is there some other way to change the keyboard bindings in the
Outlook 2007 editor?

Thanks,

John.
