I don&#39;t know if I&#39;m missing out on something, but the &#39;fullscreen&#39; function doesn&#39;t seem to work when i try to use it; I just get a &quot;Not in scope: `fullscreen&#39;<br>&quot; error.&nbsp; Am I missing out on something?&nbsp; It&#39;s a function that features in several tutorials...it&#39;s mentioned in the old documentation, but I seem not to be able to find anything about it in the new one :/<br>
