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
- `hyper-apropos' shows you functions and variables, possibly filtering only
the interactive functions and user variables.
