Base 64 decode. This is the only one I use frequently.

javascript:function%20c(){}c.prototype.get=function(){var%20a="";window.getSelection?a=window.getSelection().toString():document.selection&&"Control"!=document.selection.type&&(a=document.selection.createRange().text);return%20a};c.prototype.set=function(a){if(window.getSelection){var%20b=window.getSelection();b.rangeCount&&(b=b.getRangeAt(0),b.deleteContents(),b.insertNode(document.createTextNode(a)))}else%20document.selection&&document.selection.createRange&&(b=document.selection.createRange(),b.text=a)};try{var%20d=new%20c,e=atob(d.get());d.set(e)}catch(a){alert(a.message)};
