You can add hyperlinks within your document to provide the reader with instant access to other parts of the same document. To create one, you must first create a "bookmark" at the intended destination. Then you can create a link (hyperlink) to that bookmark elsewhere in the document.
Create the destination bookmark
You can mark the hyperlink destination with a bookmark or a heading style.
Insert a bookmark
Select an intended destination item or simply click where you want to insert a bookmark.
In the Insert ribbon menu group, Go to Links > Bookmark.
Under Bookmark name, type a name.
Important: Bookmark names must begin with a letter. After that, they can include numbers and letters, but not spaces. If you need to separate words, you can use an underscore ( _ ). For example, First_heading.
Apply a heading style to the bookmark
You must apply a heading style your new bookmark. Heading styles are used for identifying linkable destinations.
Select the bookmark to which you will apply a heading style.
On the ribbon Home > Styles area, select a heading style to apply to the bookmark.
Create a link to the bookmark
After you have created the destination bookmark, you can create a hyperlink to it.
Select the text or object you want to use as a selectable hyperlink.
Right-click and then select Link.
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.
