Unfortunately it didnt. I have been in touch with support and pretty much they have no clue and told me to pretty much leave a comment on the "feature request" portion to get a key to reset Keyboard settings -.-.
-Restarting PC (several times as I have been having the issue for around 2 weeks now)
- Running the repair function
- Fully uninstalling Home and installing again.
- Removing the Cable on the Rift directly as per your instruction.
You've tried pressing the very right button? That should put it back to the standard layout. What you are seeing is normal functionality of the Windows On-Screen Keyboard. You could also try closing the Oculus software and then opening the Windows On-Screen Keyboard by itself to change it back.
