Hello,
You can find the mentioned location when you select your root document (master page) in your content tree and switch to the Master page tab. On this tab you are able to place tags within the HEAD part of your page. You can achieve the same result by placing the
Head HTML code web part on the master page (or on any other document which you want to use the
jQuery library on) and filling that "awful" path. This path looks awful only, because slashes are encoded. You can use following code as well:
<script src="/CMSPages/GetResource.ashx?scriptfile=/CMSScripts/jquery/jquery-core.js" type="text/javascript"></script>
Best regards,
Jan Hermann
