Each of your addresses in your Address Books has a tab labeled ”Notes.” You can click on this tab and in the notes editor, you can add and format text in your note as you would in any word processor. Notes are useful for adding any extra information to your addresses, including links. Before adding a link to address notes, make sure that your address is in edit mode.
If you want your link to appear in a new browser window instead of the same browser window when it is clicked on, change the “Target” in the drop-down menu pictured above to “New window” instead of “None”.
Note: Besides clicking on the hyperlink icon, you can also right-click on any selected text and choose the hyperlink command from the context menu that appears.
