The track control area in the Trax Editor lets you lock, solo, or mute all the animation clips in a track.

Lock

Freezes the current animation track. When a track is locked, you can not edit its clips, but its animation is present during playback.

Solo

Isolates the clips on the current track so that they are the only animation sequences that are played during playback for the character. Soloing is useful when you want to isolate and review a specific animation sequence for a character. You can solo single or multiple tracks at a time.

Mute

Mutes all the clips on the current track. Muting suppresses or hides the animation on a track without removing it from the Trax Editor. Muting is useful when you want to suppress a specific animation sequence for a character during playback. See Muting animation.
