How to prevent Default screen sizing of a Webpage

ie, Disable ctrl + mouse scroll on a webpage. preventDefault() works in major browsers. It prevents the default zoom behavior so you can implement your own zoom (or something else entirely). Of course, you can not prevent someone from zooming in using the menu options, but you can prevent ctrl+scroll.

$(window).keydown(function(event) 
{
    if((event.keyCode == 107 && event.ctrlKey == true) || (event.keyCode == 109 && event.ctrlKey == true))
    {
        event.preventDefault(); 
    }

    $(window).bind('mousewheel DOMMouseScroll', function(event) 
    {
        if(event.ctrlKey == true)
        {
            event.preventDefault(); 
        }
    });
});
