Which tool can you use to change the location of the anchor point in a layer?

The Pan Behind tool is specifically designed for moving the anchor point of a layer in Adobe After Effects. This tool allows you to reposition the anchor point without shifting the layer itself, which is crucial for controlling the rotation and scaling of that layer around a specific point. When you select the Pan Behind tool, you can click and drag the anchor point to a new location, thereby determining how transformations such as rotation or scaling will behave.

Using this tool effectively allows you to manipulate the timing and movement of animations by changing the origin of transformations. For example, if you want an object to rotate around one of its edges rather than its center, you can move the anchor point to that edge using the Pan Behind tool.

The other tools mentioned do not serve this specific function. The Anchor Point tool does not exist as a distinct tool; the Selection tool allows for the selection and movement of layers but does not specifically allow for the adjustment of anchor points. The Transform tool is a general term that refers to the properties of layers (such as position, scale, and rotation) but does not enable the direct manipulation of the anchor point itself. Thus, the Pan Behind tool is the correct choice for changing the anchor point location in a layer.
