This extension enhances the Full Screen mode into a really full screen mode, hiding the remaining toolbars and statusbar and making them visible again when the mouse pointer hits an edge of the screen.
It also offers a slideshow mode, enabling @projection CSS rules in a document when full screen mode is turned on. Navigation between slides in implemented in the extension and a slide manager showing thumbnails for the slides is available through shift-F11.
See URL http://disruptive-innovations.com/zoo/fullerscreen/samples/ for sample documents (projection-test.html is also the doc for this extension, explaining how to build a slideshow document).
