Features: Customizable as a hotkey, multimedia key, etc., to achieve mouse functions, keyboard functions, game functions, string functions, and multimedia functions. The mechanical switch is triggered by a micro-switch; there's a distinct tactile feel and crisp sound when pressed. The simple dot pattern not only enhances the product's appearance but also increases friction for stability. The bottom is equipped with anti-slip pads, eliminating worries about slippage due to forceful presses. This product includes keyboard definition software for Windows systems, adaptable to various systems after configuration. (If your computer system is Unix or macOS, you must change the key definition in Windows and then reconnect the switch to Linux or macOS.) Wide application: Use it for gaming, work, machine control, machine testing, piano keyboard testing, and quick image saving.
