Step 1, open the Word21 document window and select the text, titles, paragraphs and other contents that need to be bookmarked. Switch to the Insert ribbon and click the Bookmark button in the Links group, as shown.
tip: if you need to bookmark a large paragraph of text, you can also uncheck the text and just position the insertion point cursor at the beginning of the target text.
Step 2, open the Bookmarks dialog box, enter the bookmark name in the Book Signature edit box (the book signature can only contain letters and numbers, not symbols and spaces), and click the Add button, as shown.
