The controls are:

输入	动作
Left mouse button	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.
Right mouse button	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.
Both left and right mouse button	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.
Mouse scroll wheel	Zooms the camera in and out without changing the view center.
方向键	Move the camera vertically and horizontally relative to camera viewport.
Page up and page down keys	Move the camera forwards and backwards.
Shift key	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.
Alt key	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.
Escape	Moves the camera so that entire scene is visible in the camera viewport.

Holds the current zoom-in limit. The zoom-in limit determines how close to the view center the camera can be zoomed.
