For enhanced 101-key and 102-key keyboards, extended keys include the right ALT and right CTRL keys on the main section of the keyboard; the INS, DEL, HOME, END, PAGE UP, PAGE DOWN and ARROW keys in the clusters to the left of the numeric keypad; and the Divide ("/") and ENTER keys in the numeric keypad.

  • CTRL (0x1D) UP

  • NUMLOCK (0x45) UP

The CTRL DOWN and CTRL UP events MUST both include the FASTPATH_INPUT_KBDFLAGS_EXTENDED1 flag.
