jQuery
jQuery has been added as Javascript framework, which allows many nice effects on several parts of Tiki. It is an experimental, optional feature of Tiki 3.0, and in 4.0 it is the default, always on Javascript framework. It is used in compatibility mode (via the JavaScript var $jq instead of just $) in Tiki3, 4 & 5, so specific projects can also use others (although in Tiki, it's just jQuery). However, since Tiki6, you don't need to start you code with $jq but just $.
Keep in mind that there is also a PluginJQ and Custom Code HowTo - jQuery to allow other extended usages.
It can be enabled through "Admin > Features", and its options through "Admin > Look and Feel > UI Effects"
You can see it in action in this introductory video to Tiki3#Video
