Well at least you read two whole paragraphs - the other guy got as far as two sentences. Unfortunately, it still isn't enough - here I'll cut and paste it for you then - the code and text below it hereunder are from the link I already gave. There are no intervening keys involved in the example.
    undef $ref;
    if (exists $ref->{"Some key"})    { }
    print $ref;         # prints HASH(0x80d3d5c)
