No, a tool can be designed well and still require training. It’s not the tool’s job to teach the user how to use it. > For example: ctrl+C is copy, and ctrl+V is the key right next to it for paste, making that not just muscle memory but also extremely easy to remember and even easier to explain: "press the the key to the right of C for paste". This is a terrible example. Why is it ctrl? Why is it to the right instead of the left?
