Easier accessibility access
A long-standing Apple commitment has been to assistive technology for the disabled. OS X Mountain Lion refines the assistive features in what had been called the Universal Access system preference and is now called the Accessibility system preference. The system preference has been streamlined and better organized, and it's now more easily opened through the new shortcut Option-Command-F5.
Braille support has been expanded, modifier keys are now supported in VoiceOver drag and drop, and VoiceOver now supports item dragging into hotspots. Also, the Accessibility system preference now contains the speech-commands feature that had been in the Speech system preference but were displaced from there to make room for the new dictation capability covered earlier.
