I cannot find any documentation. All I want to do it set jQuerys default animation speed. Something like this:
$.setDefaultAnimationSpeed = 5000; //does not wor
$.fx.speeds._default = 1000; // change to whatever your desired speed
or
$.fx.speeds.jojo = 1000; // adds your own speed object to jqueryspeed
