Quote marks are used for quotes, nothing else. If a word in the text makes you anxious that it might appear too much like slang or colloquialism it should either be avoided, or it should be treated just like any other word, perhaps refered to as so called.
Annotations allow you to add information to this page that would be handy to have on hand during a consultation. E.g. a website or number. This information will always show when you visit this page.
