Calling keyevent from mouse

Question

I need to emulate a key press with click on a link. The keyboard shortcut CTRL++ must be called with a click on a link, or a similar function.

    _zoomLevel += diff;
    var oDiv = document.getElementById("Contents");
    if (typeof oDiv.style.MozTransform == "string")
        oDiv.style.MozTransform = "scale(" + (_zoomLevel / 100) + ")";
    else if (typeof oDiv.style.zoom == "string")
        oDiv.style.zoom = _zoomLevel  + "%";
        else if (typeof oDiv.style.OTransform == "string")
        oDiv.style.OTransform = "scale(" + (_zoomLevel / 100) + ")";
            else if (typeof oDiv.style.WebkitTransform == "string")
        oDiv.style.WebkitTransform = "scale(" + (_zoomLevel / 100) + ")";
                else if (typeof oDiv.style.MsTransform == "string")
        oDiv.style.MsTransform = "scale(" + (_zoomLevel / 100) + ")";
                    else if (typeof oDiv.style.transform == "string")
        oDiv.style.transform = "scale(" + (_zoomLevel / 100) + ")";
}

i think it works in all browsers now.
