Hello, I have a friend that has a handicap daughter, and she has bluetooth on her wheel chair. She is able to pair the wheelchair with her moms MacBook. We need some help with a couple of things. 1) Is there a virtual onscreen keyboard like on windows that she can use on snow leopard? 2) Is there a built in voice program that can recognize her speech vs mousing to type everything. 3) If not can you recommend some software to accomplish this. Thanks for helping out a nice little girl.
