title: keypress event blocking all keyboard keys
body: <pre><code>$(document).keypress(function (e) {
      if (e.which == 13) {
          filtruj();
          return false;
      }
      return false;
  });
  </code></pre>
  
  <p>I want to call <code>filtruj()</code> whenever the user presses the <kbd>Enter</kbd> key and prevent a page submit.</p>
  
  <p>Normally this function is called with click on <code>&lt;a href="#" id="filterButton" onclick="filtruj();" class="t-button t-grid-add"&gt;Filtruj&lt;/a&gt;</code> element.</p>
  
  <p>What is happening instead is that I am unable to type anywhere in the form fields.</p>
