Trackpad functionality in free-space mode
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 Figure 7: Trackpad functionality in free-space mode on page
24.
Tapping or clicking the trackpad results in left-click gestures, which is not any different from the regular
trackpad use.
