Search the file for the keyword "doubleclick". Approximately line number 94, And right before that place paste the followin code. 

This code will enable opening links in a new tab when you hold ctrl key and clicking on the link. 

    editor.on('contentDom', function(evt){
            var isCTRL = false;

            this.document.on('click', function(ev)
            {
                var element = CKEDITOR.plugins.link.getSelectedLink( editor ) || ev.data.element;
                if (element!=undefined &&  element.is( 'a' ) ) {
                    if(isCTRL)
                    {
                        window.open(element.$.href,'_blank');
                    }
                }
            });

            editor.document.on( 'keyup', function(event)
            {
                if(event.data.$.keyCode == 17) isCTRL=false;
