A joystick control is disclosed for a change speed gearbox in which two selector are separately controllable remotely. The joystick control comprises a support body, an axle rotatably supported by the body, and an operating lever connected to the axle by a pivot pin such that the operating lever is rotatable about the axis of the axle in one plane and is pivotable relative to the axle about the axis of the pivot pin in an orthogonal plane. Two actuating members are rotatably supported by the axle and arranged one on each side of the operating lever. Each actuating member is connectible by a respective Bowden cable to one of the selectors of the gearbox and extends and retracts the cable in response to rotation of the actuating member about the axle. Mating formations on the operating lever and the actuating members allow the operating lever to be engaged selectively for rotation with one or the other of the actuating members in dependence upon the direction in which the operating lever is pivoted relative to the axle about the pivot pin.
