NOTE: You can request instructions after purchase. Function introduction: The keyboard cannot be set up for every possible function, so thank you for reading carefully. Any key 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 and convenience. One-key macro operations can be configured, where pressing one key executes a sequence of multiple keystrokes. Each macro can support up to 24 keystrokes with adjustable delay intervals. For example, one-click login or automated commands. Multimedia keys can be customized for volume control, play/pause, track navigation, and more. Mouse button functions (left, middle, right) can be assigned to keys, effectively replacing standard mouse inputs.
