an attachment for remote control of a keyboard cmprising a series of selecting elements mounted for movement in a first direction between inoperative and operative positions , each having a series of apertures ; a series of push - bars mounted for movement in a second direction , each having an elongated member oriented longitudinally in a third direction ; a plurality of push - sticks , each being rotatably linked at one of its ends to one of the elongated members of push - bars and slidably linked at its other end to an aperture of one of the selecting elements ; devices for selectively moving the selecting elements and push - bars ; a plurality of push - rods mounted for movement in the second direction , each having its lower tip suface bearing on top of the corresponding key , and its upper tip surface being acted upon by the corresponding push - stick in the direction that causes the corresponding key to move from inoperative position to operative position only when the selecting element linked to the push - stick was first moved to operative position and then the push - bar linked to the push - stick was next moved to operative position ; whereby selectively moving the selecting elements and the push - sticks selectively moves the keys of the keyboard from inoperative position to operative position and actuates consequently the functions intended for the keys .
