The Action Editor is where you can define and control actions. It enables you to view and edit the F-Curve data-blocks you defined as Actions in the F-Curve editor. So it takes place somewhere in between the low-level F-Curves, and the high-level NLA editor.
It gives you a slightly simplified view of the F-Curve data-blocks (somewhat similar to F-Curve shown without handles). The editor can list all Action data-blocks of an object at once.
Each Action data-block forms a top-level channel (see below). Note that an object can have several Constraint (one per animated constraint) and Pose (for armatures, one per animated bone) F-Curve data-blocks, and hence an action can have several of these channels.
Switch between different actions stacked/stashed on top of each other in the NLA stack, without having to go to the NLA Editor and leaving tweak mode and reentering it on the other strip.
Clicking on the up/down arrow buttons to go to the action in the NLA track above/below the NLA Strip being whose action is being tweaked in the Action Editor.
操作将单独考虑查看/编辑动作的设置(如Solo和NLA Muting )。这样做是为了更容易预览不同的暂存动作。
If moving from a solo'd NLA track to the active action, the NLA stack will be muted so that the action can be edited in isolation.
Likewise, if the NLA stack is muted when editing the action, the NLA track below it will be edited with solo enabled.
These still work when you are not editing the action used by an NLA Strip. If you are just animating a new action normally, it is possible to use the down arrow button to temporarily jump down to the previous action. Without losing the new action you are working on, and then use the up arrow button to get back to it once you are done checking the other action(s).
