pressure required on Apple keyboards
I have a disabled friend who is looking for a keyboard where only a very small pressure/force is required to activate the keys. Ideally, she would like a 0 Newton keyboard. She is not satisfied with the current infrared substitutes.
Can someone tell me what is the force required to activate a key on the Apple keyboards that are sold?
These specifications are difficult to find.
Thanks in advance.
