Patch moving with keyboard

Hi all, I have a little problem. I have created the patch object in a figure with an axes and then i have placed it at some location using the transformation. Now i want to move it using the arrows or an any other button on my keyboard.

Here is an example:

    function[] = main()

    fig....

    ax...

    set(Fig,'KeyPressFcn',@KeybordMoving);

    end

    function[] = patch()

    t=0:pi/2:2*pi;

    x=cos(t);

    y=sin(t):

    handle=patch(x,y,[0 0 0]);

    Tx=-1;

    T=makehgtform('translate', [Tx 0 0]);

    M=T;

    AxT=hgtransform('parent', gca, 'matrix', M);

    end

    function[] = KeboardMoving(hobject, event)

    switch event.Key

    case 'something'

    case 'something'

    end

end

Each press on key i would like to move it left or right. thanks for help.
