You can link to another page on the web using either text or an image (like say a button). To do it using text, you need to scroll over and highlight the text you want to use in the Text Editor and click the little Chain Link button in the tools. You can type or paste the address you want to link to in the box shown (Link URL field), making sure you have the full address ie., http://www.address.com.

You also have the opportunity to decide whether the linked page opens in the same window or a new one by selecting from the Target drop-down menu in the Link popup.

To use an Image as a link you simply upload to your page as normal, and double click on it. In the popup you type an external web address in the box provided.
