HotKey Mouse Class Filter Driver (Windows Driver)
The HotKey Mouse Class Filter Driver is a driver used on some Lenovo laptops (and possibly other brands) to enable advanced functionality for external USB mice and hotkey features. This driver is part of the broader set of software tools that enhance input device management on the laptop, particularly when it comes to handling additional features like hotkeys, gesture controls, and integration with multimedia keys or function keys on the keyboard.
In essence, the HotKey Mouse Class Filter Driver acts as a "filter" that modifies or extends the behavior of certain mouse and keyboard inputs in conjunction with hotkey functionality. It may be used to enable special shortcuts or to allow the system to recognize the use of multimedia or function keys when pressing hotkey combinations on the keyboard.
