Alternate Playlists in the Track List
When an audio track is set to Playlists view, all of its associated playlists appear listed under the track name in the Track List. The names of associated alternate playlists are indented to distinguish Playlist lanes from tracks. From the Track List you can show and hide alternate playlists. You can also access the Right-click menu for alternate playlists, which lets you apply Show or Hide, Scroll Into View, Rename, Delete, and Filter Lanes commands.
