e.which will give the homoginized code for the pressed key, then you can use a array of disabled keycodes to prevent the default action.

var disabled = [55, 107, 106]
$(document).on("keydown", ".quick-edit", function (e) {
    console.log(e.which)
    if($.inArray(e.which, disabled)!=-1){
        e.preventDefault()
    }
});
