What is touch typing and why it is more preferred?
Touch typing is a method of typing that involves centering your hands on the keyboard using a specific position. A touch typist does not look at the keyboard while typing and uses all ten fingers to type.

Using two or three fingers to hunt and peck takes much longer and allows for the development of bad habits. It is much better to keep your hands still and allow for efficient use of all fingers. Touch typing involves the specific placements of all eight fingers and both thumbs; once muscle memory is strong enough, this style allows for the typist to focus on the screen rather than the keyboard.
