Hello there, I was wondering why my top 4 Console.WriteLine’s disappear when I put the ConsoleKeyInfo variable on top of it. Or why the program does not work when I have more than one Consolekey assigned? I’m sure it is because of the Console.ReadKey(); but I’m not sure of what else to use. I’m just learning ConsoleKeys.

Console.ReadKey is blocking meaning the program will hang until you press a key. You are not seeing the writelines because the program is waiting for a key

It has nothing to do with how many ConsoleKeyInfo variables you have.
