Robots are starting to walk on their own at the same time most smartphones are bringing Virtual Reality to anyone with an extra $15 in their pocket. But there’s one aspect of technology that has remained shockingly consistent: the keyboard.
There's more going on with the average keyboard than one would think. The random assortment of letters was no accident. The bumps on the F and J keys were no accident either.
The most common letters on the QWERTY keyboard were arranged to minimize finger traffic to the popular letters. The reasoning behind this order was to slow typists down while minimizing errors. So why are there two bumps on most keyboards? It's not braille for blind typists, silly. It’s for your index fingers! The bumps are intended to ensure organization and index-finger accuracy.
Rest your hands on the keyboard with your index fingers on each bump. Feels good right? If you’re one of the few people who learned how to type the correct way than you probably already know what the F and J bumps were for, but if you’re one of those hunt-and-poke typists, then use this info to steer your typing abilities back into the right direction.
They are called Keyboard Bumps and there are addons for keyboards that don't have them.
It allows you to feel where your index fingers should rest.
