What are the keyboard controls like for this game?

i find the concept of this game really interesting but i can't even finish the tutorial with the keyboard or with a controller as some buttons aren't working on one or the other. This is really frustrating and should be so confusing on how to use the controls. my biggest thing is does anyone know what the A key is on a PS4 controller is i've tried every button and nothing works for me to switch my light lock target....
