Accessibility
Not every user has a graphic environment with a mouse or other pointing device.
Some users rely on keyboard, alternative keyboard or voice input to navigate links,
activate form controls, etc. This site is designed for keyboard access (in addition
to mouse access) and will generally be accessible to users with other input devices.
This can be crucial to people with motoric disabilities. Of course there are other
conditions where it could be necessary or useful. To take a trivial example, if
your mouse is temporarily broken, you might still wish to do some Web surfing. And
in technologies which differ from "normal" PCs or terminals, such as WebTV, laptops,
and handheld devices, a pointing device or function - if available at all - can
be significantly more difficult to use for exact pointing than a good mouse.
