in reply to what is keys %$hash_ref [-1]

The fragment you have shown will not compile. The following will compile:

(keys %$hash_ref)[-1]

... and will return the "last" key of hash %$hash_ref. But that would seem somewhat meaningless, as the keys of a hash do not have any specific order. Any apparent order of the keys may change when the elements of the hash are changed, or a different Perl is used.
