I agree. I'd never guess what NT stood for. Even if I managed to deduce what it meant and how to use it by its usage patterns, I'd still not be able to guess. It reminds me of NB -- an acronym I learned how to use from context and even began using myself occasionally, only years later realizing I didn't actually know what it stood for.
EOM, on the other hand, is immediately clear to me because of it's similarity to EOL (end-of-line) and EOF (end-of-file).
