Abstract: A hot key register request is created in an extensible firmware interface application, the hot key register request has a key number and a pointer to a hot key function for the new hot key. The hot key register request is sent to a keyboard driver in the extensible firmware interface. A hot key table is created in working storage from the hot key table in the keyboard driver, and a hot key entry is inserted into the hot key table in working storage. The entry includes the key number and pointer from the hot key register request to add the new hot key as a registered hot key. A success message is sent from the keyboard driver to the extensible firmware interface application. The success message indicates the new hot key has been registered.
