It can have a different name, and even a different mode, but I don't 
think using significantly different key bindings is a good idea while 
the buffer (except for the name, maybe) looks exactly the same. That's 
still a good recipe for confusing a user.

Perhaps we could rename the "find definitions" buffer instead, because 
that one only has one "source".

The second case, however, can have "matches" coming from very different 
sources, so calling it "grep" might not always be appropriate.
