The vision options allow the user to magnify the screen, and invert the color combinations for a white on black appearance. Speech output can also be turned on toread alerts, selected text and text underneath the mouse.
The Speech output program in the Mac is called VoiceOver.
The VoiceOver manual is available as a tagged PDF file. There is also an audio version of the VoiceOver Manual on the Voiceover downloads page on the Apple website.
There is a VoiceOver key command chart available, this is designed for sighted and partially sighted users. It is not accessible with speech output.
AssistiveWare has a product called VisioVoice. This product "enhances" access to the Mac, as it adds multilingual support to VoiceOver.
