In the Quick Find Comments text box, type in the string to search for in all comments. This can be a word or a few words. So for, example, typing redline, and running a search, returns only the comments that contain a single "redline" word.
Tip: If you don’t know the exact content of the comment, you can use the wildcards. To match one single unspecified character use the symbol “?” (question mark). To match any number of unspecified characters either before or after the text, use the symbol * (asterisk). For example, if you want to find all comments that contain some text before and after the word redline, type *redline* in the Text box.
