Toolbar sharing between Windows and macOS

When typing the command “_Walkabout” on Rhino 8 for Windows. you are promised to get a different type of navigation than the regular one. The headline of your Viewport in Rhino is also changed from “Perspective” to “WalkAbout”, but how can I use the arrow keys (or even better WASD/QE-keys) to navigate the Rhino Viewport “Escape-style” og like a shooting-game for a computer? Inspiration here: WASD controls in Rhino?
