I have wasted hours on Youtube to get my WSAD keyboard keys working in the Enhanced Input System, I am so disappointed that GameDev has not bothered to update this part of the course. In the comments several users present a successful Blueprint scheme but unfortunately a thorough step-by-step explanation is absent (the solution requires quite a bit more more than just a blueprint) and so it was near impossible to try and emulate their remedy. Ultimately I did find a working solution on Youtube. Hours too late I also discovered that you have to click your mousepointer into the play screen to give it focus otherwise the WSAD keys have no effect on your player
