The Word command listed in Undo for this action is Toggle Character Code. A
recorded macro also reflects this:
Sub Macro1()

' Macro1 Macro
' Macro recorded Friday, May 18, 2007 by Suzanne S. Barnhill
'
Selection.ToggleCharacterCode
End Sub
Note that the code (2212 in this case) does not, however, need to be
selected for this to work provided Alt+X is pressed immediately after typing
the numbers. You can, however, select any character in the document and
press Alt+X to get its corresponding character code.

Suzanne:
Thanks for the information. I guess I'm out of luck, because I just can't
find that command in Word 2000. It's not in the list of Word commands
available in the Macros dialog box, and VBE won't react to it when I type it
in. No mention in the Help either.
Must be a later innovation.
I wonder if I can cobble together an approximation.
