Final answer:
The 'Add Find/Replace text' feature is used for making multiple changes or edits to a document, enhancing the sentence-level accuracy of phrasing, grammar, and other writing mechanics.
Step-by-step explanation:
When you use the feature 'Add Find/Replace text,' you have the ability to perform multiple changes. This tool is designed to help you edit your document by allowing you to quickly make edits at the sentence level, which includes the phrasing, grammar, mechanics, and wording. As you go through your paper, it's beneficial to read your work aloud or have your device read it to you, so you can identify where changes might be necessary. Additionally, any edits made directly to your document may appear in red color or with a red strikethrough, which helps in identifying the modifications easily.
