code: function multipleFilterFn () {
    return this.choices.choices
      .filter((choice) => choice.checked)
      .map((choice) => choice.key)
  }
docs: The enquirer has a bug where it returns
  the name over the key, which is wrong.
  
  This method overrides that behavior
  
  @method multipleFilterFn
  
  @return {Array}
