You can filter which animation layers display in the Animation Layer Editor, as well as which layers display in other animation tools like the Graph Editor, Dope Sheet, and Time Slider.
You can set which display option all of the animation tools use in the Show menu of the Animation Layer Editor, or you can set the layer filtering options individually for each tool.
By default, the Time Slider displays keyframes from active and selected layers, and the Graph Editor and Dope Sheet display information for all affected layers.
