How do I move the crosshair around in PCMaster/PCPainter?

Ctrl - Move Horizontally Shift - Rotate View Shift+Ctrl - Move Vertically Mouse Wheel - Zoom

Your view is centered around the crosshairs.

Zoom out to move around more quickly/easily and then zoom back in for a more detailed view once your crosshair is where you'd like it to be.

The trajectory is a series of arrows showing the direction of travel of the Rover (LiDAR)
