This is the worst keyboard I have used in 30 years of computing. ( I'm not a touch typist, but I'm fast and accurate enough to have written extensively and to have been published.) It is far too easy to make a mistake (something to do with key design?), and this often activates hot keys that have unpredictable and usually very undesirable consequences. Look at the poor reviews on Amazon to see other unfortunate people's experiences. Probably it works fine for someone with complete accuracy, but as far as I am concerned, it will go in the trash as soon as I can find a replacement.
