You can't configure your VR and keyboard controls at the moment. What VR controller are you using? It has constant mappings for Vive and Oculus. The next update v0.55 will include SteamVR Input support so you can customize the mapping to your liking. At the moment this update will only be available to Supporter tier on my Patreon. It will be released to the public here later this month.
