Work with the hand in Auto IK mode and by directly rotating it until it looks something like the earlier illustration. Now, take a look at the Action Editor. It has several rows, or channels, and each has a name that corresponds to a bone in the active armature. When you select a bone in the 3D view, the corresponding channel in the Action Editor is selected. Just the same, RMB clicking a channel name in the Action Editor selects that bone in the 3D view. In the illustration, the channel is selected. Notice that some yellow diamonds have appeared within the Action Editor’s timeline. These represent the bones’ keyframes
