Typing without looking the keyboard

If I take a look around, at my job, and make it carefully, I can realize that are few who look the keys while they type. It's something common in programmers because we were born with a keyboard under our arm. ¿How many of you look constantly the keys for typing?

Not having to look the keyboard should be something basic to learn for those who usually use the computer. Looking the keys, it is like having to look at the shift every time we change gear in the car, it would distract us of what we are doing.

To make things easier there are several programs to help us with this task, but I don't feel like to look for them, so use Google if you're interested. ;-)

You don't need to spend a lot of time to learn, just with a little everyday the improvement is spectacular.
