Using Mac OS X Accessibility Features

What are they?

Mac OS X Panther (10.3) comes bundled with what Apple calls Universal Access. Universal Access is available via System Preferences, which can be activated from the Apple menu. There are four basic categories: Seeing, Hearing, Keyboard, and Mouse. The Speech settings in System Preferences also contains useful text-to-speech and speech recognition technology.
