This mod enables Auto running (and sprinting/swimming)! Auto climbing does work, just angle the camera in the direction you want to climb!
This mod works with the toggle sprint option in game to allow you to walk, swim, sprint, etc. at the faster speed without the need to press W! Simply press either "=" or press "F1" to enter autorun mode, then press that key again, or press "W" or "S" to stop auto running!
If you encounter issues, please let me know!
