Unity Editor RMB + WASD FPS flyby controls not working

In the videos I’ve been watching it suggests to use this WASD control method by holding down right mouse button. I am unable to get these controls to work. It appears all the controls work with the exception of the W, and the D keys. These keys make my trees and rocks disappear or reappear depending on how long I hold RMB + W or D. I have made sure my controls are set to the default. This is with unity pro in the current version.
Thanks

Make sure you’re in a perspective view before hitting RMB+W/S. it doesn’t work in an isometric view (hit the little box inside the view gizmo to switch to perspective).
