Once free-space navigation mode is enabled, the trackpad functionality changes.
Moving a finger on the trackpad does not cause the cursor to move, but results in a “scroll” motion (similarly to the scroll wheel on a mouse). Vertical movement on the trackpad causes vertical scroll, while horizontal movement results in horizontal scroll motion. This is illustrated in the following figure.
Tapping or clicking the trackpad results in left-click gestures, which is not any different from the regular trackpad use.
