Logitech MX Keys S keyboard uncomfortable switch from Logitech signature and other keyboards with gaps between Esc and F1, F4 and F5, F8 and F9. While working in applications like programming graphical design, video editing there is a lot of hotkey combinations usage. In such cases hand are not bound to standard position and while pressing some functional keys F1-F12 usually those gaps between functional keys serve as tactile mark for blindly finding the proper key to press. Maybe you could provide some addition to Logitech MX Keys S like adhesive silicon platforms which can be applied to mark gaps between functional keys. Or maybe some platforms that can be applied directly on top of key caps.
