Typing is the process of inputting text into a device, such as a typewriter, computer, or a calculator, by pressing keys on a keyboard. It can be distinguished from other means of input, such as the use of pointing devices like the computer mouse, and text input via speech recognition. User interface features such as spell checker, autocomplete and autoreplace serve to facilitate and speed up typing and to prevent or correct errors the typist may make.
The basic technique stands in contrast to search and peck typing as the typist keeps their eyes on the source copy at all times. Touch typing also involves the use of the home row method, where typists keep their wrists up, rather than resting them on a desk or keyboard as this can cause carpal tunnel syndrome. To avoid this, typists using this method should sit up tall leaning slightly forward from the waist, place their feet flat on the floor in front of them with one foot slightly in front of the other, keeping their elbows close to their sides with their forearms slanted slightly upward to the keyboard, fingers should be curved slightly resting on the home row (asdfjkl;).
Many touch typists also use keyboard shortcuts or hotkeys when typing on a computer. This allows them to edit their document without having to take their hands off the keyboard to use a mouse. An example of a keyboard shortcut is touching the Control key plus the S key to save your copy as you type or the Control key plus the Z key to undo a mistake. Many experienced typists can feel or sense when they've made an error and can hit the backspace key and make the correction without missing a beat.
Search and peck (two-fingered typing or peck and run) is a common form of typing, in which the typist must find and press each key individually. This is almost always considerably slower than touch typing. Instead of relying on the memorized position of keys, the typist must find each key by sight. Use of this method may also prevent the typist from being able to see what has been typed without glancing away from the keys. Although good accuracy may be achieved, any typing errors that are made may not be noticed immediately, if at all. There is also the disadvantage that because fewer fingers are used, they are forced to move a much greater distance
