With hyperlinks, you can link a word or group of words to a different page or post on your website.
To create a hyperlink, highlight the text you want to link and click on the Insert/edit link icon*. An input box will appear, where you can type or paste the URL you want to link. Once you are done, hit enter and Save your changes.
*To see the Insert/edit link icon, you need to make sure the Visual tab is selected on your text editor (top right corner of the editor).
