By way of example, if you follow this link

http://caselaw.lp.findlaw.com/scripts/getcase.p...

you will, ordinarily, get FindLaw's very busy, ad-heavy page. This script will redirect you to the printer-friendly version. The script also converts all links to cited Supreme Court cases in the opinion to the printer-friendly version.

Because FindLaw's pages take so long to load (because they're so busy and ad-heavy), the original redirection takes rather a long time. Hitting the 'Esc' key once as the page is still loading speeds you to the printer-friendly page. (There is apparently no way to do that in the script.)

There are still annoyances about the FindLaw site, but this reduces some of them. In particular, navigating in the printer-friendly space seems to avoid the annoying sign-in demands which come after following a couple of links.
