If you continue to press the Tab key, you will enter the Flash movie where you will see the focus rectangle for the two buttons. If you do not have a screen reader or up-to-date version of the Flash plugin (7+), then the focus will remain trapped within the Flash movie and you will not be able to navigate to the link at the bottom of this page.
Those using Mozilla, Netscape 7, or Opera will notice that the Flash content is skipped entirely when navigating with the Tab key (or Q and A keys in Opera). To access the elements within the Flash movie with these browsers, you must use the mouse to click within the movie. At this point, you will then no longer be able to navigate outside of the Flash movie without using the mouse.
For someone that does not have an up-to-date Flash plugin, the rest of the content on this Web page is now totally inaccessile. Even if you refresh the page or leave the page and come back, Flash will not relenquish it's hold on the focus. The only way to access the rest of the content on this page is to click above or below the Flash movie with the mouse or close and restart your browser, return to this page, then ensure that you do not click in or navigate to the Flash movie.
