A bookmark in Word works like a bookmark you might place in a book: It marks a place you want to find again easily. You can enter as many bookmarks as you want to your document, and you can give each one a unique name so they’re easy to identify.
To add a bookmark, you first mark the location in your document you want to go to. After that, you can jump to the location or add links to it within your document.
Bookmark the location
Select text, a picture, or a place in your document where you want to insert a bookmark.
Click Insert > Bookmark.
Under Bookmark name, type a name and click Add.
Note: Bookmark names need to begin with a letter. They can include both numbers and letters, but not spaces. If you need to separate words, you can use an underscore ( _ )—for example, First_heading.
Go to the bookmarked location
After creating your bookmarks, you can add links to them within your document or jump to them at any time.
Jump to a bookmark
Go to a bookmark by typing Ctrl+G to show the Go To tab in the Find and Replace dialog box. Under Go to what, click Bookmark. Enter or choose the bookmark name and click Go To.
Link to a bookmark
You can also add hyperlinks that will take you to a bookmarked location in the same document.
Select the text or object you want to use as a hyperlink.
Right-click and then click Hyperlink .
Under Link to, click Place in This Document.
In the list, select the heading or bookmark that you want to link to.
Note: To customize the Screen Tip that appears when you rest the pointer over the hyperlink, click ScreenTip, and then type the text that you want.
