NOTE: You can request instructions after purchase Function introduction The keyboard cannot be set up for everything, so thank you for reading clearly. Any keys on the standard Windows keyboard can be customized and fully replaced. One-key shortcut functions can be set, allowing a single press to replace multiple keystrokes, improving efficiency. One-key macro operations can be programmed, where pressing one key executes a sequence of keystrokes with customizable intervals (up to 34 bits per macro). Example: one-click input. Multimedia controls such as volume up/down, next/previous track, play/pause can be assigned. Mouse button functions (left, middle, right) can be customized, replacing physical mouse buttons. Features: HID plug-and-play compatible with Windows 7 and above, Linux, and macOS. No driver required. Built-in memory retains settings; no need to reconfigure when switching devices. Works across multiple computers and supports multiple keyboards connected simultaneously. Simple software setup requires only a Windows system. Functions like a standard keyboard in most scenarios and supports some BIOS configurations. Supports multiple language layouts. Key rollover without ghosting supports up to 6 simultaneous key presses, all registering accurately. The slim bar-style keyboard includes non-slip strips. For added stability, attach the anti-slip pads at both ends. Remaining units ship with non-slip mats. Detachable cable design allows easy unplugging for convenient office portability.
