Link Properties Question

Permalink
Under link properties, the second tab is called "Target." In that tab, there is a drop-down menu called "Target." The menu contains eight or so items. Where can I find a detailed description of what they all do? In fact, where can I find a detailed description of what all the fields in link properties do?

Thanks.
