Should have noted that I'm using mouse and keyboard, skip cutscene is set up properly but I really need to change the grab and rotate buttons and can't seen to figure out where they are in the .txt file

Been watching MikeWave's tutorials, gotten pretty good on Ps4 but wanted to start running the Steam version. Only issue is I know how to change my controls with the .txt file but I don't what what I should change or what I should change them to, hoping someone can help!
