Accessibility note: There are shortcuts defined for the entries of the navigation menu. If your browser supports them, you can quickly access these entries by hitting "Alt + Digit" (Opera-Browser: first press "Shift + Esc", then "Digit"). Whereas "Digit" refers to a digit between 1 and 5. A digit is assigend to each entry of the menu, starting on the left with 1 ("Home"), 2 ("Contents") and so on until the last defined digit 5 ("About...") is reached.
