title: How can we select suggestion on tab key instead of Enter key in mat-autocomplete angular 6?
body: <p>As <strong>MatAutocomplete</strong> (Angular 6) has default behavior of <strong><code>keydown</code></strong> and <strong><code>keyup</code></strong> for option selection and <strong><code>Enter</code></strong> for the input value of selection.</p>
  
  <p>I want to use <code>tab</code> instead of <code>enter</code> key.</p>
  
  <p>Please suggest</p>
  
  <p>Code:</p>
  
  <pre><code>&lt;input matInput [matAutocomplete]="origin"&gt;
  &lt;i class="material-icons search-form-icon"&gt;place&lt;/i&gt;
  
  &lt;mat-autocomplete #origin="matAutocomplete"&gt;
      &lt;mat-option  *ngFor="let v of originList" [value]="v.value"&gt; {{v.text}} &lt;/mat-option&gt;
  &lt;/mat-autocomplete&gt;
  </code></pre>
