Typing


Typing is the process of inputting text into a device, such as a typewritercell phonecomputer, or a calculator, by pressing keys on akeyboard. It can be distinguished from other means of input, such as the use of pointing devices like the computer mouse, and text input viaspeech recognition.
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 checkerautocomplete, and autoreplace serve to facilitate and speed up typing and to prevent or correct errors the typist may make.
A computer keyboard is divided into sections according to function type. The alphanumeric and typing keys function in much the same way as a typewriter. The numeric keypad works like a traditional adding machine so you can enter numbers quickly. The control keys, used either alone or in combination with other keys, perform specific actions. The function keys each perform a specific program task. The navigation keys move your cursor around a document or Web page.

  • Each finger rests on a particular key in the home row of the keyboard when not typing, in order to keep "grounded" and oriented at all times. The home keys (ASDF JKL; ) are outlined in yellow on the above diagram. The thumbs remain in the air, or very gently in contact with the keys below.
  • Each finger is responsible for a vertical column of keys, which you can think of as a "home column". The column is not straight up and down, but rather slopes up to the left.
  • Both index fingers are responsible for an additional column, the one next to their home columns towards the middle of the keyboard.
  • The thumbs are used for the space bar, and depending on the shape of your keyboard can also be used for the "command" (Apple computers) or "Windows" (PCs) key.
  • The left-hand pinky is also responsible for all the keys to the left of its home column, including the left shift key, caps lock, tab, tilde, escape and others.
  • The right-hand pinky is a real workhorse, covering everything to the right of its home column. Take a look - there's a lot of stuff there! 
  • typing is real fun!!!
