Bookmarking things within gmail

Restoring a Firefox session accidentally told me that, when you open messages/chats in a new window, you get an url that you can bookmark/copy to another file. Nice.

Exploring things a bit further showed that gmail uses frames, so you can use the url of the inner frame to bookmark contacts, labels, filters, searches or any other thing that does not have the "New Window" link. In Firefox, use the popup menu, and "This Frame > Open frame in new tab".

Very handy for those of us that run our lifes in tiddlywikis.

Of course, Google is perfectly free to change these misterious urls not likely intended for public consumption...
