Microsoft Natural Ergonomic 4000 Keyboard is built on a very sturdy base; very thick wrist-rest is built in. You’ve got the forward and backward buttons for Internet surfing; num lock and scroll lock indicator lights, as well as your favorites button and macro keys up here. Calculator button and your usual layout here, except there’s a zoom button now. As you can see, it’s more ergonomic. You’ve got your home button, your search, your mail – these can all be mapped to different applications with the included software. Your hand, as I mentioned in another video, is resting more naturally than a traditional keyboard, and it uses USB. It’s a wired keyboard, as you can see it’s very thick. There’s two stands here, and with this grey-black finish, overall it looks really nice. Here at Mr. Tech Reviewers, we reviewed many keyboards before, but never an ergonomic one such as the Microsoft one you see here today. So those who are suffering from carpal tunnel syndrome should give this a try. It would actually make a pretty good gaming keyboard because of all these extra buttons up here; you can map them to different functions.
