I want to use my keyboard to copy and paste in command prompt instead of using a mouse to do it. I noticed that using CTRL + V didn't work. Here is an easy way to copy + paste in Command Prompt. After you've copied your text use the following keys on your keyboard: Alt + Space e p. That's all you need to remember. Press Alt + Space on your keyboard, then press e and then press p. Keep doing it and you'll get used to it.
