Action Editor

While the Dope Sheet mode lets you work with keyframes of many objects at the same time, the Action Editor mode focuses on the keyframes inside a single action.

An action is a reusable animation segment – a collection of F-curves, where each curve describes how a certain property changes over time. Objects can reference one action as their active action and additional ones through Nonlinear Animation tracks.

Previous/Next Layer (down/up arrows)

Switches to editing the action in the track below/above the current one, automatically entering or leaving Tweak Mode as necessary. Also transfers the Disable NLA stack setting to the Solo setting and vice versa (see NLA tracks).

Push Down (strips with down arrow icon)

Creates a new NLA track below the Action Track and moves the active action into it. This is the same as clicking Push Down Action in the NLA editor.

Stash (snowflake icon)

Creates a new muted NLA track at the bottom and moves the active action into it. In effect, this sets the action aside for later use, disabling it so it no longer affects the animation. Later, you can choose to either unmute it again or delete it.

If you click New Action in the data-block menu for an object that already has an active action, that previous action will be stashed automatically.

Note

Both Push Down and Stash leave the object without an active action (meaning the Action Editor becomes empty and the action can no longer be edited). If you still want to make changes to the action, you can select it in the NLA editor and press Tab to enter Tweak Mode, or use the Previous/Next Layer buttons as described above.
