While current animation is paused, the selected bone become the target bone for the current animation framekey. Rotation controls target to the selected bone in the current framekey.
Rotation has three control sliders for each local bone axis of x, y, z. Every slider ends with a number input control for fine-adjust.
Rotation controls have range limits from
-180 degrees up to 180 degress by step of one degrees.
Notice that axes x, y, z refer to the target bone local axes, not to scene global axes.
