Sometimes, hyperlinks are scary. You ask yourself, "Do I really want to leave the page I'm on?"
This is especially true when reading documentation, policies, procedures, and job aids.
If you see a link (like this link here) in a knowledge base article, you don't want to click on it because you don't want to leave the help article you're on. After all, if you leave, there's a chance you'll never find your way back.
