You mean, something like a std::map but one key can correspond to
multiple values?  You might try doing this:

        std::map< key_type, std::list<value_type> >

I'm not sure what you mean by "multiple keys," but if you mean you want
multiple key types all mapping to the same set of data, you can simply
use multiple maps, and use pointers for the value_type (so accessing a
value_type object from any map will return a pointer to one object,
rather than a copy stored in each map).  You have to be careful, in that
case, to remove an object from all maps before calling delete on the
pointer.
