The Programmable Hotkeys driver is a software component that enables the functionality of programmable keys on your keyboard or external device (such as a multimedia keyboard or a specific type of specialized keyboard, mouse, or external controller). These "hotkeys" are customizable keys that can be programmed to perform specific actions or launch specific applications when pressed.

For example, you might have a keyboard that includes dedicated hotkeys for controlling volume, media playback, opening websites, or launching programs. The Programmable Hotkeys driver allows you to define these actions and integrate them with your operating system or specific software.
