This is far outside my level of comfort, and I'm facing a very interesting sitaution. Essentially, I'm dealing with a massive hash. I have access to the hash reference, and I want to traverse the hash and take out the names of the other hashes and their keys. I want to ignore values. Using Data::Dumper is unreadable due to size.

Let me show an example. Note that this is all inside the main hash reference 

    'flags' => {
    'example' => 0,
    'font_attributes' => {
      'size' => -1,
      'colors' => ''
    },
    'Redacted' => 0,
    'Redacted' => [],
    'font_changes' => {
      'size' => -1,
      'colors' => -1
    },
    'Redacted' => 0,
    'Redacted2' => -1,
    'Redacted3' => -1,
    'Redacted4' => 0
  },
  'Domains' => {},
  'removed_results' => [],
  'Words' => {},
  'other_results' => {},
  'recipient_list' => [
    'test@test.com'
  ],
  'Clean' => {
    'extra' => {}
  },
  'result' => 'pass',
  'Lists' => {
    'Body' => {
      'RedactedWordList' => {
        'words' => {
          'word1' => '5',
          'word2' => '1',
        },
        'words_found' => [],
        'weight' => 0
      }
    }
}

As you can tell, it just keeps going and going and going and going. I want to be able to print everything except the values. So $startingHash with hashes within it, and those hashes having hashes within them. I want to print the name of every "hash name" and every "key" in a readable format. I can't seem to wrap my brain around how I could do that. I'm tasked with documenting everything available within this mega hash, but I don't need the actual value obviously
