We Can Surely Say That You Don't Know The Reason Why Keyboard's "F" and "J" Have Line ridges!

Have you ever noticed why the ‘F’ and ‘J’ keys have a line on them? And sometimes the ‘5’ key on the numeric keypad? And Don't even think that it is for production defect, nor is it for any health benefits.

The raised lines on the ‘J’ and ‘F’ keys are placed there for proper position of fingers while typing.

For ease of use of the keyboard, these keys have lines on them so that if you are speed-typing without looking at the keyboard a lot, then the ridges will help you position your fingers if in case you fly off the handle.

For the correct typing position, the ridges are placed on those two keys so that you place your index fingers on them.

Positioning your left index finger on the ‘F’ key and your right index finger on the ‘J’ key leaves the other three fingers of your left hand to rest on the ‘D,’ ‘S,’ and ‘A’ keys while the remaining fingers of your right hand rest on the ‘K,’ ‘L,’ and ‘:/;’ (colon) keys. The thumbs of both hands should ideally rest on the space bar.
