If you use perldoc.perl.org and you find the magically floating navigation header that follows you as you scroll to be annoying, relief is at hand. Grab the CSS patch at userstyles.org and apply it in your browser. Firefox users should install the Stylish extension to enable the functionality; Opera and Greasemonkey users can run it as a userscript instead. IE users lose out as far as I know, but I'd be happy to be corrected :)
