The channels region is used to select and manage the curves for the Graph editor. This part shows the objects and their animation data hierarchy each as headers. Each level can be expanded/collapsed by the small arrow to the left of its header.
- Name Filter
Only displays channels that match the search text. Pressing the invert button displays all channels except the channels that match the search text.
On the headers, there are toggles to control channel's setting:
- Pin (pin icon)
Make the channel always visible regardless of the current selection (Graph editor only).
- Hide (eye icon)
Hides the channel(s)/curve (Graph editor only).
- Modifiers (wrench icon)
Deactivates the F-curve modifiers of the selected curve or all curves in the channel.
- Mute (speaker icon)
Deactivates the channel/curve.
- Lock (padlock icon) Tab
Toggle channel/curve from being editable. Selected channels can be locked by pressing Tab.
In the Dope Sheet this is also working inside the NLA, but that it does not prevent edition of the underlying F-curve.
