renderScaleKey() {
    if (this.scaleKey === false) return '';
    if (this.state.submitted) return '';
    let scale = this.scale.map(item => `   ${item.name} - ${item.message}`);
    let key = ['', ...scale].map(item => this.styles.muted(item));
    return key.join('\n');
  }
Render the scale "Key". Something like:
@return {String}
