From the patch 2.2.0 notes:
New Features
Global
- Users can now modify their keybindings, including camera controls, by changing values in the keydefaults.lua file in the Settings folder. The keydefaults.lua file will not exist until you first launch a multiplayer game after the patch. Please see the contents of keydefaults.lua for more information
But I can't find this Settings folder.
Where is it? Or is there a better way of changing the key bindings?
