+    \class Qt3DExtras::QOrbitCameraController
+    \brief The QOrbitCameraController class allows controlling the scene camera along orbital path.
+    \inmodule Qt3DExtras
+    \since 5.7
+    \inherits Qt3DCore::QEntity
+
+    The controls are:
+    \table
+    \header
+        \li Input
+        \li Action
+    \row
+        \li Left mouse button
+        \li While the left mouse button is pressed, mouse movement along x-axis moves the camera
+        left and right and movement along y-axis moves it up and down.
+    \row
+        \li Right mouse button
+        \li While the right mouse button is pressed, mouse movement along x-axis pans the camera
+        around the camera view center and movement along y-axis tilts it around the camera
+        view center.
+    \row
+        \li Both left and right mouse button
+        \li While both the left and the right mouse button are pressed, mouse movement along y-axis
+        zooms the camera in and out without changing the view center.
+    \row
+        \li Arrow keys
+        \li Move the camera vertically and horizontally relative to camera viewport.
+    \row
+        \li Page up and page down keys
+        \li Move the camera forwards and backwards.
+    \row
+        \li Shift key
+        \li Changes the behavior of the up and down arrow keys to zoom the camera in and out
+        without changing the view center. The other movement keys are disabled.
+    \row
+        \li Alt key
+        \li Changes the behovior of the arrow keys to pan and tilt the camera around the view
+        center. Disables the page up and page down keys.
