Why are there bumps on the F and J keys on a computer keyboard?
Keyboards are supposed to be used by not looking at them, and while everyone gets used to it, these two keys can help you at the initial stage or if you get stuck all of a sudden. If you keep the thumbs on the spacebar, your index finger will be directly placed on the F and J buttons on the keyboard.
The left hand can then cover ASDFG keysThe right can take care of JKL and the colon.
This helps you get your hands in the right position and type when there is no backlight or typing in low light. These keys are referred to as the home row. If you make a habit of following these keys every time you start typing, it will result in muscle memory. So if you need to find a key, you will not think about it, and your fingers will do the job. It is similar to why Piano players position at a certain place every time before they start. It is also an accessibility feature that allows people with special abilities to figure out where to start if they need to use these types of keyboards. Overall, these bumps or ridges will help to improve your efficiency at the keyboard, increasing your typing speeds. You should always have your fingers over the home keys and move your finger back and forth when typing. I hope it is now clear, that why keyboards come with bumps on the F and J keys on the computer keyboard. Read next: What do Keyboard F1 to F12 Function Keys do?
