define REQUIRED_MODS = MOD_LCTRL | MOD_LSHIFT;

int modifiers;

main {
    modifiers = get_modifiers(REQUIRED_MODS);

    if(modifiers == REQUIRED_MODS && get_keyboard(KEY_SPACE)) {
        set_val(PS5_CROSS, 100);
    }
}

What it teaches: modifier masks, exact-mask comparison, keyboard usage constants.
