Lock and mute tracks
Lock a track to prevent editing the track or its contents. Mute a track to hide the effect its signals and clips have on your scene. A track can be both locked and muted.
For example, you can lock an Animation track when you have finished creating a cut-scene and you want to avoid inadvertently modifying its Animation clips. You can mute an Audio track if you want to stop its audio from playing while you edit other tracks and clips in your Timeline instance.
