AKA bookmarklets. Saw these mentioned on pidster.com yesterday, and then blow me, saw one in action today... as I get it it's the art of putting a little bit of javascript in as a bookmark / favourite... I've not done this exactly, but the new "approve" links are a bit like this...

Get latitude and longitude from google maps
They're mostly not very useful to anyone else, but help yourselves...
