With this tool, you can add up to four handles anywhere in the image. Then you can move one of these handles and a transformation will be applied so that the other handles stay in their place.
The type of transformation depends on the number of handles:
1 Handle: Move
2 Handles: Rotate and scale (keep aspect ratio)
3 Handles: Shear and scale (don't keep aspect ratio)
4 Handles: Perspective transform
This tool is useful for example when you made two photos of an object and want to transform one of them so that they fit on each other.
