The UltraBoard 950 Wireless is the newest compact keyboard from BakkerElkhuizen.
Because it is wireless, has rechargeable batteries and works with both Windows and macOS, this keyboard will meet all your needs.
The biggest difference with a standard keyboard is that there is no numeric keypad, which makes the keyboard smaller.
With a compact keyboard the reaching distance to the mouse is smaller, reducing the load on your forearms. Another advantage is that a more compact variant is easier to transport in a laptop case, so you do not have to depend on your laptop keyboard.
