To add relax/force on mouse clicks, open ingame menu, select setup, then go to options, on top you will see Mouse Buttons, change it to 1.
Another way is to press X on keyboard when you are selecting a joint to relax/force
C key is to force/relax all joints at once
To see both tori's ghosts just press B on the keyboard.
Hope this helped you, cheers. Any further questions feel free to ask.
