    Code:
    /* executed when a special key is pressed */
    void keyboardSpecialDown(int k, int x, int y) {
    
    }
    
    /* executed when a special key is released */
    void keyboardSpecialUp(int k, int x, int y) {
    
    }

    But the "Ctrl" key _IS_ a special key, so should be possible to capture with that callback.

    I don't actually see a control key in glut.h. Just make your app print out whatever the call back receives and see if it's supported.
