Good point, but msdn defines the syntactic renaming as “Enables you replace text *within* a specific object. The command is similar to Find and replace.”, so I guess it won’t work across objects.

I tested it (with 2 classes) and it works as advertised, but it doens’t update other instances unless you select them as well.
And I can’t seem to get it working with tablefields…

Maybe if you select them all, or update the cross reference… Either way, it’s not the full blown reliable refactoring other software (like Eclipse) has.
