This is why I bound `C-h o' to `apropos' - I think Sam> of it as an "extra junk" apropos.

Yes, there's also another difference between the two (I don't know how it works under emacs): both commands can return a slightly different list if given a prefix (or according to inner variables): - `apropos' shows you all symbols, possibly adding unbound ones and key bindings, - `hyper-apropos' shows you functions and variables, possibly filtering only the interactive functions and user variables. -- / / _ _ Didier Verna http://www.inf.enst.fr/~verna/ - / / - / / /_/ / E.N.S.T.
