The Viewport

Next in our tour of the Unreal editor is the Viewport. This displays our currently loaded level and can be configured to make navigation easier. There are two ways to move the camera around in the Viewport:

•  Mouse and WASD: Holding the right mouse button down will let you rotate the camera, while using the WASD keys will move the camera forward/backward and left/right. Anyone with experience in Unity will be used to this camera movement.
•  Mouse only: It is also possible to navigate using only the mouse, which people with experience in previous Unreal editors will be familiar with. Holding the left mouse button will let you move the camera along the horizontal plane along with looking left/right. Holding the right mouse button will keep the camera in place while letting you look around. Holding both the left and right mouse buttons will let you move the camera up/down and left/right at the same time while keeping the rotation the same. Combining these three mouse button combinations will let you navigate a level without needing to use the keyboard.
