Other uses for target include specifying a different frame. This is typically used by menus in a navigation bar frame that pop content into a main frame.

There are several pseudo names such as _new. The other one you may use is _top which specifies that the page be opened outside of any frame. This is useful when you want to return to your home page. Here's an example:

<a href="index.html" target="_top"> Home </a>
