You can switch between two different versions ("modes") of this website
by clicking
on the link in the top left corner of any standard page. The two modes are
:
Javascript enabled mode displays the main and secondary menus
in narrow frames at the top and sides
with a full version of the chosen page in a main frame with its
own scroll bars. This is usually easier to use, but your browser needs to be running
Javascript.
Basic mode combines the menus and the contents into a single
page with the menus at the top. This should always be available, but may be
more difficult to use.
