Well, I mean you wouldn't really need to know the spelling. It would be picking the methods from the code, having parsed it. There would be no spelling involved. It's just a matter of it checking that its target is correct-- "Is this the one you wanted to change?" And if the dev doesn't know the answer to that, then they couldn't have made the change without the tool, either.
