title: Not to show keyboard when focusing a searchbox
body: <p>I am developing an app (in Xamarin.Forms) which will be used with an external barcode scanner, so <strong>I don't need to show</strong> the tactile <strong>keyboard</strong> each time I put the focus in an entry/searchbox/etc.</p>
  
  <p>How can I do this?</p>
  
  <p>Thanks guys.</p>
