If you've ever used a computer keyboard, you might have noticed the small bumps or little ridges on the F and J keys. These subtle notches are not random – they serve a crucial purpose for both novice and professional typists. Here’s a closer look at Why are there bumps on the F and J keys of a keyboard and how they improve typing skills.

Why are there bumps on the F and J keys of a keyboard? The Purpose of the Bumps

The bumps on the F and J keys are designed to help users find the home row on a QWERTY keyboard without needing to look down. In touch typing, the index fingers of each hand are supposed to rest on these two keys – the F key for the left index finger and the J key for the right index finger. These bumps act as tactile guides for the typist to quickly position their fingers correctly on the keyboard.

This feature is especially helpful for touch typists, who rely on muscle memory rather than visual cues to find the correct keys. As a result, they can maintain very high speeds while typing because their hands always return to the optimal placement of hands on the home row.

A Brief History

The idea for the bumps on the F and J keys was pioneered by June E. Botich, who helped develop these small bumpsas a way to improve the key position for typists. The keytronic keyboard, an early model, incorporated this design to enhance typing speed and accuracy. Today, most standard QWERTY keyboards, whether mechanical or digital, feature these raised bumps on the F & J keys.

Why These Two Keys?

On a QWERTY keyboard, the home row (the middle row of keys) is where your fingers should rest while typing. The little bumps on the F and J keys ensure that your index fingers are in the right position, which allows the rest of your fingers to naturally fall into place on the adjacent keys. With the right hand's fingers positioned on J, K, L, and ;, and the left hand's fingers on A, S, D, and F, you're ready to reach all the other keys without looking down.

This makes it easier to access everything from keyboard shortcuts to frequently used letters, while maintaining a comfortable and efficient typing posture.

Improving Typing Skills with Muscle Memory

The idea behind these raised bumps is rooted in muscle memory. As you continue to practice typing, your fingers develop the ability to automatically return to the home keys without thinking. This allows for blind typing, meaning you can type without needing to look at the keyboard at all.

For those aiming to improve their typing, focusing on placing the index fingers on the little ridges of the F & J keys is a great starting point. With consistent practice, the hands learn to return to the right position after pressing any key, whether you're typing letters, numbers, or using the space bar.

Conclusion: Why are there bumps on the F and J keys of a keyboard

The small notches on the F and J keys may seem insignificant, but they play a vital role in efficient and accurate typing. By providing a tactile guide for key position, these bumps allow for faster, more accurate typing by helping the hands find the home row without looking down. For both beginners and professional typists, the design of the F and J keys is an essential part of mastering touch typing and achieving very high speeds on a computer keyboard.

Next time you sit down at your keyboard, give a nod to the genius of June E. Botich and the simple yet effective design of those raised bumps. They are the unsung heroes of the modern typing experience!
