Navigation bookmarklets

Back 2

javascript:window.history.go(-2)

Back 3

javascript:window.history.go(-3)

If you want to go back two or three pages then your browser history menu will take you there in a couple of clicks. But these bookmarklets will do it in one.

Previous Page in New Window
javascript:dOc7rB3=document.referrer.toString();if%20((dOc7rB3!='')&&(dOc7rB3.indexOf('javascript://')==-1))%20{void(window.open(document.referrer,%20'prevPage'))}%20else%20{alert('No%20previous%20page.')}

Going back a page just to check something can be a hassle, as you then have to step forward and reload the next page. As an alternative, use this bookmarklet to open your previous page in a new window or tab.

Duplicate Page
javascript:dT30FfN3b=new%20Date();void(window.open(location.href,'w'+dT30FfN3b.getTime()))

Another option is to open a new window or tab with a copy of whatever page you're viewing, so you can follow links on one and quickly return to the original page in the other.

Up
javascript:void(location.href=location.href.substring(0,location.href.substring(0,location.href.length-1).lastIndexOf('/')+1))

This bookmarklet will back you out of a lengthy URL, one directory at a time. So as you click it you'll move from www.domain.com/directory/page.html, to www.domain.com/directory, then www.domain.com (if the site allows this, anyway).

Random link
javascript:void(location.href=document.links[Math.round((document.links.length-1)*Math.random())])

If you can't decide where to go next then click here, and the bookmarklet will take you to a random link on the current page.

Robots.txt
javascript:void(location.href='http://'%20+%20location.host%20+%20'/robots.txt')

Alternatively, use our next bookmarklet to view robots.txt for the current site. This file is used to tell search engines that they shouldn't index particular areas of a site, and may point you to interesting hidden areas.
