Where is the list of animate options?


I see in this documentation http://ionicframework.com/docs/api/service/$ionicModal/

fromTemplateUrl has an animate option which is set to slide in. I can’t see to find where the list of options are for other animations? I click on the $ionicModel thing and it takes me to here which explains one of the options are “animation”:


But again, no list of options. Could I ask where I can find this information? Even with googling I am unable to find it.
