Selected and highlited input after entering input by external devices like barcode reader
<p>I am using a barcode reader to fill an input field.</p>

<p>when i read the barcode usind the device <strong>product-id</strong> will be automatically filled in the input field.
when i trigger the device twice the input field will be filled twice with same <strong>product-id</strong>.</p>

<p>So i need the input field  selected and <strong>ready to replace</strong> after each iput from the device.</p>
