Instead of breaking at the word breaks in a CamelCase word, MS Word wants to put in breaks in really stupid locations - not even where the breaks are in the words if they were standalone. Under the layout ribbon there's a "hyphenation" button, and under "manual" you can pick a break point, but you can only pick from it's stupid options. You can't tell it some are bad or insert new ones. For example look at
GeneOrGeneProductOrVariant
you get breaks in these locations:
Ge-neOrGenePro-duc-tOrVar-i-ant
.
The only other options I see in the hyphenation menu appears to turn it off globally for the document?
