Simple javascript that blurs out all the links that have href="#" when you hold down the apple key (change it to something else if you don't like it). Requires jQuery, imagine that.

$(function() {
    function getColor(item){
        var rgb = $(item).css('color');
        return rgb.substring(4, rgb.length - 1);
    }

    $(window).keydown(function(e) {
        if (e.keyCode == 224) {
            $('a[href=#]').each(function(i, element) {
                var item = $(element);
                var color = getColor(item);
                item.data('color', color);
                item.css('color', 'rgba(' + color + ', .2)');
                item.css('text-shadow', 'rgb(' + color + ') 0 0 2px');
            });
        }
    });
    $(window).keyup(function(e) {
        if (e.keyCode == 224) {
            $('a[href=#]').each(function(i, element) {
                var item = $(element);
                var color = item.data('color');
                item.css('color', 'rgba(' + color + ', 1)');
                item.css('text-shadow', 'none');
            });
        }
    });
});
