My problem with that is that it makes virtually zero sense to have a "save" option in the browser. Seriously, when is the only time that was what you wanted? :) Perhaps if it was remapped to "bookmark"? (C-d? Seriously?)

Though, I should say that it was a quick trip to firemacs to get the behavior I wanted.

Yeah, bookmarking makes some sense, and is probably more useful than saving the page itself which, I agree, is almost entirely useless. To be honest, if it comes to it, I'd rather have no mapping at all for a shortcut whose standard command is out-of-place for a given app, than overload a shortcut that has a single specific meaning in every other.

I've used save several times when I wanted some information on the web page to be accessible offline. Commonly: ticket information. Or, all the information on some table on Wikipedia.
