marking in F & J keys alone in the keyboard? (make SAMSUNG)?

thats where the pointer fingers go on a standard keyboard?

What the Knight said. Reference point for touch typists.

to help vision impaired and touch typers as well people like me working in the dark, too stupid too turn the light on (or look down at the keyboard).

Actually, you will find its like that on most keyboards, because it marks where your index fingers should be in their normal or starting positions.

Prolly for blind people...Although why would they need the use of a PC...Hmm, I don't know.

if assumption serves me then they are they correct finger positioning for the blind.if this is not correct i wouldlike to knowGood question
