In the Trax editor, an interface control that exists for each level in the Trax hierarchy and gives you a high level of control over the collection of tracks under a character, group, or subcharacter.

You can collapse and expand summaries for characters, subcharacters, or groups by clicking the arrow that is beside each of their names in their respective summaries.

Each summary contains a summary clip, which you click-drag to move all the clips in all the tracks under the character, group, or subcharacter in the summary. You can also Shift+drag a summary clip to scale it.

See Trax Editor.
