How to detect Click + [Shift, Ctrl, Alt] in reactjs click event?

Your click handling function would have a format as such:

clickHandler: function (event, value) {

   event.stopPropagation();

   // In that case, event.ctrlKey does the trick.
   if (event.ctrlKey) {
        console.debug("Ctrl+click has just happened!");
   }
}
