In the Properties editor, add Action selectors to the Material
properties and the Camera properties.
For the Material, two Action selectors are shown: for the Material
itself and for its shader node tree. Those are separate IDs of different
types, and thus will always have separate Actions (until the Slotted
Actions are commonplace).
When the 'Slotted Actions' experimental feature is enabled, also show
the Action Slot selector underneath each Action selector.
The Animation panel in the Properties editor is (by default) always at
the bottom, just above the Custom Properties panel.
