Unity's Animation Window can be used to edit animations inside Unity. The official documentation and tutorials like Working with Animations and Animation Curves explain how to use it, so this page only explains a few differences when using it with Animancer.
Normally the window would get its animations from the Animator Controller, but if you select an object with an
AnimancerComponent with the Animation window open it will automatically try to find all animations in components in the same hierarchy as that object to show in the list of animations for you to choose from (including direct references to
AnimationClips as well as Transitions):
This is implemented using the
IAnimationClipSource interface in the
Creating New Animations
Creating new animations using the Animation window will automatically create a new Animator Controller which is not needed when using Animancer, so you can either delete it or use the
Assets/Create/Animation menu function instead to create just an Animation Clip.
