Using AGOpenGPS with a joystick

Hello, maybe also usefull:

        // AB-Line aktivate

        if (keyData == (Keys.K))
        {
            btnABLine.PerformClick();
            return true;    // indicate that you handled this keystroke
        }

        // AB-Curve aktivate

        if (keyData == (Keys.I))
        {
            btnCurve.PerformClick();
            return true;    // indicate that you handled this keystroke
        }

Does someone know how to implement:

  1. U-turn Left / Uturn Right button

  2. Drive in

         // drive in
    
         if (keyData == (Keys.E))
         {
             btnInField_Click.PerformClick();
             return true;    // indicate that you handled this keystroke
         }
    

btnInField_Click.PerformanceClick() does not work:
Failure: btnInField_Click is not declarted
