You can edit a glossary term, if necessary, from the Glossary Editor. In addition to changing the text of the term itself, you can change the tooltip, select a different attachment for the definition link, or change the markup conditions (match whole word, match case). You make these changes in the same way as when you add a new glossary term.
Note: Glossary terms can include both spaces and special characters, and there is no limit to the length of a term. However, each term must include at least one non-space character and cannot begin or end with one or more spaces. In addition, glossary terms must be unique, on a case-insensitive basis, within a glossary document. Therefore, for example, one glossary cannot include both the terms "document" and "Document". You must enter a valid term before you can set any of the properties of the glossary entry (definition link, tooltip, markup conditions).
After editing one or more glossary terms, you should update glossary links to apply your changes.
