Step 1: Enter your content. From there you will highlight the word(s) that you wish to link. In this case I have chosen "feature." You will then click the link button in the panel (looks like a chain link).
Step 2: Copy the url of the website you wish to link to. Paste that link in the box next to Link URL. Your target determines how you want to open the link (same window or new window). The title is the text that you wish to display as the link. In this case it is "feature."
Step 3: Click on insert and proceed normally.
