Work fast, comfortably, and efficiently on the Logitech MX Keys S Graphite. The keys are shaped to your fingertips, so you can type quickly and smoothly. It's also silent, so you can concentrate on you work. The keyboard backlight only turns on when your fingers get close to the keys, just like with its predecessor: the MX Keys. This new model adjusts the brightness of the light to the ambient light. You can also connect the MX Keys S to up to 3 devices via Bluetooth or with the included Logi Bolt receiver. That way, you can work on your Windows laptop, MacBook, and iPad at the same time. Switch devices with the touch of a button. You can get the most out of your MX Keys S with the Logi Options+ software. Set up shortcuts, light settings, and connect it to your Master 3S mouse.
