Here it is:

    javascript:(function(){document.styleSheets[0].addRule(".highlighted_to_remove","background:red !important");var e=function(e){if(e.keyCode==27){i()}};document.addEventListener("keydown",e);var t=function(e){e.stopPropagation();this.classList.add("highlighted_to_remove");return false};var n=function(e){e.stopPropagation();this.classList.remove("highlighted_to_remove");return false};var r=function(e){this.parentNode.removeChild(this);i();e.preventDefault();e.stopPropagation();return false};var i=function(){var i=0;var s=document;while(s=document.body.getElementsByTagName("*").item(i++)){s.removeEventListener("mouseover",t);s.removeEventListener("mouseout",n);s.removeEventListener("click",r);s.classList.remove("highlighted_to_remove")}document.removeEventListener("keydown",e)};var s=0;var o=document;while(o=document.body.getElementsByTagName("*").item(s++)){o.addEventListener("mouseover",t);o.addEventListener("mouseout",n);o.addEventListener("click",r)}})()

This is what I have in my "Kill Element" bookmarklet. (SECURITY NOTE: You should never blindly copy and paste javascript like this and run it in your browser.)

Your comment makes this page have a long horizontal scroll, and a total pain in the ass to read now. Perhaps you can edit that and put in spaces so it wraps? Thanks.

In fairness, this is HN's fault - not allowing posts to mess up the whole page is basic fit-for-purposeness for forum software and the whole reason HTML is not allowed in the first place. Your workaround, on the other hand, breaks the content as bookmarklets are always one-liners. Evidently (according to a sibling comment) the solution is to prepend 4 spaces, which isn't exactly standard.

As for the bookmarklet, smashing stuff. I'm always deleting irritating stuff on pages using the inspector.

not blaming anyone, just wanna be able to read the comments :)

Please prepend four spaces to this - you have broken formatting on the entire page.
