CustomEase Facilitates creating custom bezier eases with the GreenSock Custom Ease Builder tool.
 EaseLookup EaseLookup enables you to find the easing function associated with a particular name (String), like "strongEaseOut" which can be useful when loading in XML data that comes in as Strings but needs to be translated to native function references.
 FastEase TweenMax (AS3 only) has built-in algorithms that speed up the processing of certain easing equations but in order to take advantage of those optimizations, you must activate the easing equations first (you only need to activate them ONCE in your swf).
 RoughEase Most easing equations give a smooth, gradual transition between the start and end values, but RoughEase provides an easy way to get a rough, jagged effect instead.
