Trivia of jumbled keys: We know that typewriters were in full swing before the invention of laptops, and they had proper ABCD, arrangement. People became pro in typing and their speed was making the buttons jammed and in turn slowed down the printing. Then our man named Christopher Sholes (American Inventor) came up with the idea of jumbling the keys on the keyboard and invented the QWERTY keyboard which we still use. For coding, understanding the placement of keys and also the symbols is very important. So I personally recommend to first learn, few basics of fast typing without looking at the keyboard then we can code faster.
