Product Description No HID driver required. After setup on Windows 7 and above, it's plug-and-play on Linux, macOS, and Windows systems. It has a memory function, so you don't need to reset it next time. After setup, it can also be used on other computers. This keyboard can connect to multiple keyboards and function normally. The software is simple and easy to use; just prepare your Windows system for direct setup. It's almost identical to a regular keyboard, suitable for most scenarios, and supports some BIOS versions. It supports multi-key error-free operation, allowing up to 6 keys to be pressed simultaneously, with all keys responding. The key cable is detachable and can be plugged and unplugged freely for convenient office portability. Note: This keyboard cannot be configured with all functions. Any key on a standard Windows keyboard can be configured and completely replaced. It supports setting one-key shortcuts, shortening the distance between multiple keystrokes with a single press, eliminating worries about keys going out of bounds! It supports setting one-key macro operations, where pressing one key is equivalent to pressing multiple single keys consecutively. Each key on the keyboard has a total length of 34 bits, and key intervals can also be added. For example, one-key password. Multimedia keys can be configured, such as volume up/down, music up/down, play/pause, etc. The left, middle, and right mouse buttons can be configured to replace the three mouse buttons. Note: Due to the 3D printing technology used in the keyboard casing, the appearance texture may vary from batch to batch, but this will not affect its use.
