Thomas,
Adding words to the User Dictionary using a Dictionary Management Tool is
one of the best things you can do to improve the accuracy of handwriting
recognition. This is particularly important if you are working with
lexicons that are specialized. The recongizers (Latin-based) are
word/segment based, not character based. With the correct words in your
User Dictionary, you can even mispell the word and it will be recognized.
Even if you don't convert ink to text, having it correctly recognized is
important for searching notes.
Unfortunately, OneNote doesn't access a correction interface like the TIP so
adding words to the User Dictionary involves an additional step.
You can find additional information at the website in my sig.
