Spell check to consider camelCase and words_with_underscores as multiple words
As an enterprise software developer, I use Office for mockups and documentation. Method names, in particular, quickly become covered in red squiggles and I don't care to ignore each case. A simple checkbox to treat camelCase as separate words, another for words with underscores, and maybe even a way to not auto-capitalize camelCase and words with underscores would make working in Office on software-related documents much more pleasant.
I find it hard to believe this has only got 3 votes after 2 years!
(Maybe there are issues with the relevance of search results?)
Making this a standard spell check feature across Word, Excel, etc. would be a major boon for anyone interested in QA of software documentation, design documentation, etc.
