This is a new function which I have encounter with this Forte WordPress Theme, This admin panel is actually very useful for navigation and only admin who are signed-in will have this functions available for them.
It is actually the same with the admin panel you have on your wp-admin, but this make your task much faster and easier. Although WordPress 2.5 may have difference in the name of the Navigation, the function remains the same.
This is how it looks like when I am logged-on into my admin panel, and you could see my a shortcut for Dashboard, Write, Blogroll, Manage, Comments, Presentation, Plugins, Users, Option, Style and Logout.
I have edited slightly, the style function have been removed because it does not work with some themes. Also, the arrangement is previously dependent on a CSS files, since it is not viewable by visitor, there is not much need for it to look beautiful rather it is important for the navigation to be easy.
Here is an example which I have tried on my other blog.
