The present invention provides for a room temperature cured silicone thermoplastic resin sealant composition with reduced gas permeability useful in the manufacture of glazing such as windows and doors. Since the card slot depth can be made smaller than the conventional one so that the card can be inserted into the reader apparatus without hiding the information attached at the predetermined position, the user can view the information. A detent system may be provided to hold the first and second cam levers in a pre-staged position in which open ends of the cam grooves of the first and second cam levers are aligned, andor in a fully assembled position. The gesture event gate determines whether a corresponding gesture event is passed to an application that is active in the view.
