Large Key Keyboard. Customizable, programmable USB macro keyboard with one key. HID drive-free. After setup, it works with Linux and macOS (version 7 and above) and is plug-and-play. The memory function eliminates the need for reconfiguration. Once set up, it can be used with a different computer. Multiple keyboards can be connected and used normally. Easy software operation; you can set it up directly, just prepare your system. Almost like a regular keyboard, it's suitable for most situations and supports some BIOS versions. Multi-key design without punch-out keys; supports up to 6 keys pressed simultaneously, and all will register. The key cable is detachable, making it convenient for carrying around the office. NOTE: The keyboard cannot be configured for all functions. All keys on a standard keyboard can be customized, and these keys can be completely replaced. One-key combinations can be set up just once to reduce the time it takes to press multiple keys, and don't worry about them being out of reach! One-key macro operations can be configured. Pressing a single key is equivalent to pressing multiple individual keys simultaneously. The total length of each key on the keyboard is 34 bits, and the interval time can also be added. For example, a one-click password. Several multimedia keys can be configured, such as volume up/down, music up/down, and pause. The left, middle, and right mouse buttons can be configured to replace the three mouse buttons. Note: Because the keyboard cover is 3D printed, the appearance and texture may vary slightly from batch to batch, but this does not affect its use.
