Dope Sheet

The Track View — Dope Sheet editor displays keyframes over time on a horizontal graph. This graphical display simplifies the process of adjusting animation timing because you can see all keys at once in a spreadsheet-type format.

You can select any or all of the keys in a scene, scale them, move them, copy and paste them or otherwise work directly here, rather than working with objects in viewports. You can choose to select the keys for children, or subtree or both, so you can make simple changes that affect many objects and their keys at once.

Dope Sheet allows for soft-selection of keys which is very useful when working with motion capture data that has keys on every frame.

Dope Sheet provides tools for working directly with Time. You can Select, Cut, Copy, Paste, Insert and Reverse Time using the tools found on the Time menu.
