Keyboard navigation

This site can be navigated by keyboard. These keys are available:

Key	Action
space bar, n	next page
p	previous page
s	first page
i	index page

(Please do not confuse these actions with your browsers back and forward buttons or shortkeys which refer to your browsing history.)

JavaScript needs to be turned on to enable this feature.

Navigation bar

Another way to move around is to use the navigation bar offered by our slides. Unfortunately, only a few browsers support this HTML feature (Opera, for example, can display the bar).

Hierarchie path

Every (contents) page provides a navigation path, located right below the page title. This path shows the complete hierarchie of the current page. Each level is a link which can be used to jump to the related chapter.

Browser

Although Internet Explorer is widely used, it does not support CSS fully. We recommend Opera or a Gecko Browser (Mozilla, Netscape) for reading.
