Typing is the process of writing or inputting text by pressing keys on a typewriter, keyboard, cell phone, or a calculator. It can be distinguished from other means of text input, such as handwriting and speech recognition. Text can be of the form of letters, numbers and other symbols. The world’s first typist was Lillian Sholes from Wisconsin. She was the daughter of Christopher Sholes, the man who invented the first practical typewriter. User interface features such as spell checker and autocomplete serve to facilitate and speed up typing and to prevent or correct errors the typist may make.
