I have trouble remembering all the things I can do and how, so I went looking for a list of commands and controls for the PC version of Witcher 3. The only one I found was woefully incomplete. So, here you go. I just brought up the keybindings and scribbled stuff down, so any mistakes are my own fault and I’d love to hear what they are so I can make this more useful.
