Bumps on F and J keys help you type faster

Have you ever noticed tiny bumps on the F and J keys of a keyboard?

Those bumps are there for a very good reason.

They are called tactile markers or home-row markers.

They help your fingers find the right starting spot without you looking down.

When you type, your left index finger should rest on F and your right index finger on J. Your other fingers then line up naturally on the keys around them.

If your hands start to drift, you can feel the bumps and fix your position.

This helps you type faster and make fewer mistakes.

The idea is very old and comes from typewriters.

Even though keyboards changed over time, the bumps stayed because they are so useful.
