If accessed from Viewpoint, Edit Current Viewpoint , the Edit Viewpoint dialog box allows editing of the current viewpoint's attributes.

Enter the Roll of the camera about its viewing axis. This value is not editable where the world up vector stays upright (i.e. in walk, orbit and turntable modes).
Enter the speed of motion in a straight line for the viewpoint in the Linear Speed box (the minimum value is 0 and the maximum is based on the size of the scene's bounding box).
