   what,pattern: name of an object, or regular expression to
             match against

   where, numeric.: a logical indicating whether positions in
             the search list should also be returned

       mode: character; if not `"any"', only objects who's
             `mode(.)' equals `mode' are searched.

   simple.words: logical; if `TRUE', the `what' argument is
             only searched as whole only word.

        `apropos' returns a vector of character strings giving
        the names of all objects in the search list matching
        `pattern'.  If `mode != "any"' only those objects which
        are of mode `mode' are considered.  If `where' is
        `TRUE', their position in the search list is returned
        as their names attribute.

        `find' is a different user interface to the same task
        as `apropos'.  However, by default (`simple.words ==
        TRUE'), only full words are searched.

        `objects' for listing objects from one place, `search'
