Keyboard Bumps
If you look at a computer keyboard, any keyboard, you’ll notice two little bumps on both the F and J keys. If you ever took a class in high school on how to type, you probably know why those bumps exist on those keys. For the rest of you, those bumps are there so users can find their way on the keyboard while keeping their eyes on the screen. If you are typing with two hands the proper way, your hands will be set up so that your left pointer finger is on F and your right pointer finger is on J. Without having to look at the keyboard, you just have to feel these bumps with your fingers to know that your hands are aligned properly and ready to get to work.
