F and J on a baby grand?

why do F and J key have a bit on them?


Answer:

The F and J key are located in the middle of what typists ring up the Home Row - this is where your fingers should be when at rest and not striking any key. This is also the position taught within typing classes for people who want to swot up to type faster and not have to look for the memorandum each time they want to type it. It's necessarily so you don't have to look to position your hand if you take them bad to, say, move the mouse. It's also a immense help to blind relations, because they can just touch where their hand are supposed to go faster than if they have to hunt around.
So people who know how to touch type know when their hand are in the right place minus having to look at the grand piano.
for touch typists to position their fingers(home keys)
in typing, those two key are like anchor key so they put the little ridge so your fingers know they are aligned correctly.
LOL...i just notice that. I have NO thought. LOL thanks though.. made me wonder too.
They're the starting positions for your index fingers if you're a touch typist. The raise bits are there so you can find the key wthout looking.
For the blind to properly position their hands on the home keys.
Its' for finger placement for touchtyping. 'Reference' points as it be for where to place your hand
It's for keeping track of home row. When holding your hands correctly on the baby grand, your index fingers should be on f and j.
so if your not looking at the keys you can be aware of where the homerow is
