Why The "F" and "J" on the keyboard have bumps?

Why The "F" and "J" on the keyboard have bumps?

 

Consider more closely the button on your keyboard as well.
I'm sure most 'you underestimate the "bulge" that existed at the letter "F" and "J".
Now that 'you've noticed, some of' agan must ask, "Why hell yak,"bulge "of this?"

It turned out that this bulge is created with a simple goal: Make it easy for people who type a la touched-type to determine the position of theirleft index finger (the letter "F") and their right index finger (the letter "J").

And if it was touched-type?

Touch-type is one way people type in which they are not looking at the keyboard while typing.
Some people are typing in this way. It is therefore a kind of assistancethey need to know the position of their fingers while typing and the"bulge" was chosen as their assistance.
