To delete an entry from your index in Microsoft Word, select the entire index field in your document. Make sure to include the braces surrounding the field. Then, press Delete.
You may not see the index field in your document. In that case, click the Show/Hide button in the Paragraph section of the Home tab.
After you delete an index entry, you’ll want to update the index, if it has already been created. Open the References tab. Click Update Index in the Index section.
