URL Target Properties
The URL target property allows configuration of a target window id or frame id in which a link URL is displayed – it corresponds to the target attribute of the the HTML <a> tag. The first time a user clicks on the link, the browser will open a new window with the specified id; subsequent clicks are directed to the same window. If a target is omitted, the link will display in the same window.
The following special target names can also be used. Consult any HTML reference for further information.
