Here’s a handy(?) script to delete pieces of any page you’re on when you click on them:
Go to any page on the web, paste it into the address bar of your browser and then start clicking around. It works okay in IE6 and Firefox – I haven’t tried it in anything else but it should be okay in IE5 (PC), and might work in Safari.
Try it out by clicking on this link and then clicking around on the page.
