  public constructor(props:IPivotTilesProps){
    super(props);
    this.state = { 
      // .... stuff deleted //
    };
    // .... stuff deleted //
    this.onLinkClick = this.onLinkClick.bind(this);
  }
  // .... stuff deleted //
  public render(): React.ReactElement<IPivotTilesProps> {
    // .... stuff deleted //
    return (
              <Pivot 
                style={{ flexGrow: 1, paddingLeft: '10px' }}
                linkSize= { pivotOptionsGroup.getPivSize(this.props.setPivSize) }
                linkFormat= { pivotOptionsGroup.getPivFormat(this.props.setPivFormat) }
                onLinkClick= { this.onLinkClick.bind(this) }  //{this.specialClick.bind(this)}
                defaultSelectedKey={ defIndex }
                headersOnly={true}>
                  {this.createPivots(this.state,this.props)}
              </Pivot>
     );
}

  public onLinkClick = (item): void => {
 
    console.log('onLinkClick item: ', item); // This will get me information about the Pivot I clicked on (need heading)
    console.log('onLinkClick this: ', this); // This will get me the react component's "this"
    
    //UPDATE THIS IS WHAT WORKS:
    //   If you try to refer to "event" directly (event.ctrlKey) it does not work.
    //   BUT if you assign it to e first, then it works :)
    let e: any = event;

    if (e.ctrlKey) {      
      //window.open(this.props.listWebURL, '_blank');
      //event.preventDefault();
      //return ;
      alert('Hi! CTRL key was pressed!  ' + item.props.headerText);
    }

    // NOTE:  This was my original code WHICH DID NOT WORK... See notes above.
    // But I also need to find a way to get the event so I can tell if any special keys are pressed...
    // I copied this code from another component's onClick and I can get both props and the event by just passing in the event.
    // The only difference is in my other component, I'm not passing it to an Office UI Fabric component
    
    // What I want is perform extra action if the CTRL-key is pressed when clicking.
    if (event.ctrlKey) {      
      //window.open(this.props.listWebURL, '_blank'); // My current code gets the link to open
      //event.preventDefault();
      //return ;
      alert('Hi! CTRL key was pressed!');
    }
