タイトルにリンクを付けます。
javascript:(function(){var c="<div style='background-color:white;opacity:0.9;position:fixed;z-index:9999;width:90%;'id='linkId'><div style='width:98%;padding:4px;'><div style='float:right;'onclick='var elem = document.getElementById(\"linkId\");elem.parentNode.removeChild(elem);'>☒</div></div><textarea onclick='this.select();'style='border:none;width:98%;'rows='20'>";c+="["+document.title+"]("+location.href+")";c+="</textarea></div>";document.body.innerHTML=c+document.body.innerHTML;})();
見やすく
javascript:(function(){ var c="<div style='background-color:white;opacity:0.9;position:fixed;z-index:9999;width:90%;'id='linkId'><div style='width:98%;padding:4px;'><div style='float:right;'onclick='var elem = document.getElementById(\"linkId\");elem.parentNode.removeChild(elem);'>☒</div></div><textarea onclick='this.select();'style='border:none;width:98%;'rows='20'>"; c+="["+document.title+"]("+location.href+")"; c+="</textarea></div>"; document.body.innerHTML=c+document.body.innerHTML; })();
(追記)Aタグも
