Type without looking?

Today at Enrich we did a letter typing game, except the only catch was that we had to do it without looking. I was quite good at it! I found it quite hard, even right now as I am typing this I am not looking (just for practice).

The words we had to type weren't actually words but random letters containing the letters asdf, they were simple and quite easy for me but I could not type as fast as I would normally with looking. But typing without looking at what you are doing makes you not realize mistakes that you make during this but I still need to look for caps lock and commas and the rest which is bit hard to find without looking.

Overall I found it most enjoyable but frustrating when it would not type because I forgot a space!
