Anchors are especially useful if you want to link to a particular spot (sentence, paragraph, image) in a rather long page.
 

First you need to insert an anchor at the spot that will be the destination for the link.
 

• Open the Text and Image Properties by clicking the icon next to the text.

• Position the cursor at the desired place within the text and press the Insert Anchor button . A small Anchor icon will appear at that spot in the text.

• To edit the anchor name - click on the Anchor icon . The Anchor toolbar will open to the right. Write the new name in the Name field.

• To make the Anchor available as a link destination - Press  .
   

After you have inserted an anchor - you can make a link to it from the same oranother page, a menu or a gallery image. Let's make a text link.

• In the Text and Images properties - select the word you want to make a link.

• Then from the Link dropdown on top of the editor choose the Page where we inserted the anchor.

• A second dropdown will appear with all available anchors on that page. Select the desired one.

• Press to submit the changes to the page.

Don't forget to publish in order to make the link available in Normal View too.
