NOTE: You can request instructions after purchase. Function Introduction: The keyboard cannot be programmed for every function, so please read the details carefully. Any key on a 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 accessibility. One-key macro operations can be programmed, where pressing one key simulates a sequence of multiple keys. Each macro can have up to 34 key entries, with adjustable delay intervals between keystrokes, enabling functions such as one-click login. Multimedia keys can be customized for volume control, track navigation, play/pause, and more. The left, middle, and right mouse button functions can also be assigned to keys, effectively replacing basic mouse operations.
