{
    KMOD_NONE = 0x0000,
    KMOD_LSHIFT = 0x0001,
    KMOD_RSHIFT = 0x0002,
    KMOD_LCTRL = 0x0040,
    KMOD_RCTRL = 0x0080,
    KMOD_LALT = 0x0100,
    KMOD_RALT = 0x0200,
    KMOD_LGUI = 0x0400,
    KMOD_RGUI = 0x0800,

    KMOD_CAPS = 0x2000,
    KMOD_MODE = 0x4000,
    KMOD_SCROLL = 0x8000,

    KMOD_CTRL = KMOD_LCTRL | KMOD_RCTRL,
    KMOD_SHIFT = KMOD_LSHIFT | KMOD_RSHIFT,
    KMOD_ALT = KMOD_LALT | KMOD_RALT,
    KMOD_GUI = KMOD_LGUI | KMOD_RGUI,
