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. The basic technique stands in contrast to hunt 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. A highly trained touch-typist on a Dvorak keyboard is the second-fastest method of English text entry available as of 2007[citation needed]. (The fastest text entry method involves a highly trained typist on a stenotype keyboard).
