jQuery mouseover delay

    var showDelay = 500; //will be delayed half a second
    var showTimer = null;

    $('#elementId').live('mouseover', function()
    {
        if (showTimer)//if there is already such event this cancels the setTimeout()
            clearTimeout(showTimer);
        showTimer = setTimeout(function() //executes a code some time in the future
        {
            //you can put here the script that should be delayed
            $('#otherElement').css('display', 'block');
        }, showDelay);
    });
