The same movements you’ve seen in the article Move the observer in Navigation window with your mouse, can be achieved by using the keyboard buttons. There are predefined buttons that allow you to navigate the scene, and you can customize them as you prefer.
If you click Configuration button in the Ribbon (Navigation group) you open a mask where to see the current setup, change it as you need and even adjust the mouse rotation and speed. The current setup is the standard one in PC gaming. In the next image you can see the Navigation customization mask.
Note that you can use both keyboard and mouse movements in order to walk quicker in the room: why don’t you try to keep the left mouse button pressed in order to set direction, and W (keep it pressed too and release when reaching destination) keyboard button in order to go forward.
