Hi everyone from Brisbane Australia,
Another great way to navigate in Blender is by pressing SHIFT+F (Windows). This will enter flight mode and you can control the camera with the WASD keys (great if you are also used to using Unreal Engine 4).
While in flight mode you can press TAB or G to toggle gravity, SHIFT for fast movement, ALT for precision movement, SPACE (or middle mouse) to ‘teleport’ to an object, V to ‘jump’ (if gravity is enabled), Q to descend and E to ascend and also use the scroll wheel on your mouse to adjust the speed of movement manually.
EDIT Just realised this is covered in section 1 lecture 13 >.<
