How to add Keys in Graph Editor

1, Open Graph Editor: Windows -> Graph Editor.

2, Select the target object that want to keyframe.

3, Select the target attributes of object that want to keyframe.

If the attribute was created by self, make sure the it’s keyable.

Otherwise warning was popped when add key:

Current manipulator and active objects have no keyable attributes, or animation layers are present and the BaseAnimation bar is not selected or locked.

4, Hit S (or Alt + I) to insert a key at certain frame.

Or right click Channel Box -> Key Selected.

5, Hold Middle Mouse Button to move the key.

Anim Cueve Example: animCurveTU

1, Change the keyable method.
By default, all keyable attributes will be set key when hitting S, even you just select only one attribute.

But we want to set key only for selected attributes.

Solution:
Key -> Set Key options.

Select All keyable attributes, then select From Channel Box.

2, Add a keyable attribute:

3, Select the target attribute, then hit S to set key.
When the Key was set, you can move the key by hold MMB.

After hitting S, an new node will be created automatically in Node Editor: animCurveTU. aaa

If can’t see animCurveTU node, click Input connections.

4, Adjust the frame range.

Make sure the animCurveTU node was selected in Node Editor before adjust keyframe parameters, otherwise anim curve will be lost in animCurveTU.

5, Set key by Hit S.

You can also delete key by Hit Del, or click: Key -> Delete Keys.

6, Set the key value, then straighten anim curve.

7, Build the driven process for attribute.

End result:
Make sure the Offset Parent Matrix of bone was optimized.

8, Finally, we can fine tune toe rotation by tweak attribute.

战国战争史：秦灭巴蜀之战
秦灭巴蜀之战，于周慎靓王五年（公元前316年），秦国张仪、司马错等率军攻灭巴国（今四川东部）、蜀国（今四川西部）的战争。
此战，先击灭巴、蜀及苴等各国(均在今四川境)，占领秦岭外广大地区，达到了进一步“富国”、“广地”、“强兵”目的，战略上还形成对楚的侧翼包围，为尔后南进创造了有利态势。 秦灭巴蜀，为进一步灭楚和统一六国准备了条件。
