title: How to Enable ctr + scrollwheel to zoom in Google Maps Api
body: <p>Hi im using Google Maps API <a href="https://angular-maps.com/" rel="nofollow noreferrer">https://angular-maps.com/</a>, and i want to zoom only while pressing ctrl + scrolling with the scrollwheel. Reading the documentation I have found this:</p>
  
  <blockquote>
    <p>gestureHandling    This setting controls how gestures on the map are
    handled. Allowed values:</p>
    
    <p>'cooperative' (Two-finger touch gestures pan and zoom the map.
    One-finger touch gestures are not handled by the map.)  'greedy' (All
    touch gestures pan or zoom the map.)  'none' (The map cannot be panned
    or zoomed by user gestures.)  'auto' [default] (Gesture handling is
    either cooperative or greedy, depending on whether the page is
    scrollable or not. Type: |||</p>
    
    <p>Default value: auto</p>
  </blockquote>
  
  <p>so in my code i added :</p>
  
  <pre><code>&lt;agm-map
      [latitude]="lat" 
      [longitude]="lng"
      [zoom]="zoom"
      [gestureHandling]="cooperative"
      [mapTypeControl]="true"
      [mapTypeControlOptions]="mapType"
      &gt;
  </code></pre>
  
  <p>but is not working, it does not ask me to press ctrl to zoom.</p>
