<p>The <code>isTrusted</code> read-only property of the <a href="https://developer.mozilla.org/en-US/docs/Web/API/Event"><code>Event</code></a>
interface is a <code>Boolean</code> that is <code>true</code> when the event
was generated by a user action such as mouse click, and <code>false</code> when
the event was scripted or invoked via
<a href="https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/dispatchEvent"><code>dispatchEvent</code></a>.</p>
<p>This new property is intended primarily for use by browser extensions, to
determine if an event was dispatched by a script running in the main world or
not.</p>
