Where can I find this command?
The TiltView command rotates the view around the axis formed by the line between the view camera and target.
Steps
Click and drag in a viewport to tilt the view.
Note: When the cursor moves near the right and left viewport edges, a snapping mode is enabled. The view rotation snaps in five-degree increments. The keyboard shortcut, Shift + Alt + Right mouse button displays an "s" to indicate the snap mode is on.
Command-line options

Note: This is a one-time tilt, not a drag.

Right
