Frank Edward McGurrin, a court stenographer from Salt Lake City, Utah who taught typing classes, reportedly invented touch typing in 1888. On a standard keyboard for English speakers the home row keys are: 'ASDF' for the left hand and 'JKL;' for the right hand.
The keyboard is called a QWERTY keyboard because these are the first six letters on the keyboard. Most modern computer keyboards have a raised dot or bar on the home keys for the index fingers to help touch typists maintain and rediscover the correct position on the keyboard quickly with no need to look at the keys. More recently, the ability to touch type on touchscreen phones has been made possible with the use of specialized virtual keyboard software for touch typing.
