In order to add a link, you will want to do the following:
- Highlight the text that you want to be the hyperlink.
- Click on the icon in the toolbar that looks like a globe with a chain link on it (
).
- You will then see the link dialogue.

In general, you won't need to change the Link Type or the Protocol settings. They should be URL and http://, respectively. If you do change them, you need to know what you are doing and you probably wouldn't be reading this FAQ entry.
- In the URL text box, put the URL of the page you are trying to link to. Make sure that you do not include the http:// in this text box, as that will fail to link properly.
- Click on OK.
