Find bindings for all modes

[Tim Johnson]

I'm using emacs 24 on Mac OS X, console mode, macports install. 

When I do something like this
C-h c C-j

I am told that the binding for C-j is 
electric-newline-and-maybe-indent
in Fundamental mode.

But from *scratch* the binding is 
eval-print-last-sexp
in Lisp Interaction mode

Is there a way to find out all mode - specific bindings for a given
key sequence?

Thanks
