Utilizing links in content is great for referencing other content but you don't always want the actual link to be spelled out in all it's super long glory. Many times you'd like the link to be hidden into the content seamlessly integrated.
To make a link that is not the actual link URL, all you need to do is highlight the text you would like to be a link and click the link button. It will ask you what the URL is for the link and you can paste it in the field or use the search feature to find the page you would like to link to by starting to type. Then click on the checkmark to save. You should now have the text you highlighted link to the URL you entered.
