In Word 2002, I stupidly made Cntrl+B the shortcut to a style,
forgetting that it's for making text bold.

Now I can't remember what style I applied it to.

I want to go back to that style and change it to something else.

So:

--How can I find out which style has that Cntrl+B shortcut key?

--Will going back and changing the shortcut for that stye to something
else, automatically get back the bold function for Cntrl+B? If not,
how do I do so?

--(Unrelated) How do I make sure when I create or modify a style, that
it's available for all documents, old or new?

Thanks!!
