title: Leaflet.js: Use ctrl + scroll to zoom the map & Move map with two fingers on mobile
body: <p>I'm using <a href="http://leafletjs.com/" rel="noreferrer">http://leafletjs.com/</a> ... is it possible to only: </p>
  
  <ol>
  <li><p>Use ctrl + scroll to zoom the map </p></li>
  <li><p>Move map with two fingers on mobile/tablet</p></li>
  </ol>
  
  <p>... so similar what google maps does? With the comments ...</p>
  
  <p>So far thats my setup:</p>
  
  <pre><code>// Leaflet Maps
  var contactmap = L.map('contact-map', {
          center: [41.3947688, 2.0787279], 
          zoom: 15,
          scrollWheelZoom: false
      });
  </code></pre>
