Before adding a link to a Document, make sure that your Document 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”.

How to insert links to email addresses
If you want to create a link to an email address, follow the steps as you would when you insert any other link. Instead of typing a web URL into the URL field of the pop-up window, put in an email address prefaced with “mailto:”. For example, “mailto:email@example.com”. Clicking on this link tells your browser to launch your email program with this address in the “To” field.
