Enable panning gestures—Assists with navigation when panning maps, scenes, and layout views. When you click and release the mouse, the application assists in navigating toward the direction the mouse was released, like a push or pull to glide in that direction. This option is checked by default. If you uncheck this option, the assistance is not provided.
