In Word 2004 and earlier it's accessible by choosing Tool menu => Customize
=> Customize keyboard => Categories: File, Commands: FileSaveAs => assign
the shortcut and, if desired, get rid of F12.
Note: In Word 2008, which I don't use yet, this information may be
accessible through a different interface. If that's relevant, check back
soon in case someone modifies what I've said.
Obscure? :-|
