When I try to select multiple rows using the Ctrl key then the border of the selected td is blue.
I am using this code to check whether the Ctrl key is pressed or not:
$("#unSelectedTab td").click(function (event) {
        if (event.ctrlKey) {
            $(this).toggleClass("backgroundcolor");
        }
        else {
            $("#unSelectedTab td").removeClass("backgroundcolor");
            $(this).addClass("backgroundcolor");
        }
    });
