==== Using the keyboard ====
The keyboard is usually the main device to providing instructions to the computer. The keys on the keyboard can be divided into several groups based on function:
# Typing (alphabets and numbers) keys: These keys are arranged as in a traditional 'QWERTY' typewriter
# Special purpose keys: These keys are used alone or in combination with other keys to perform certain actions, such as CTRL, ALT, ESC, Function keys etc.
# Navigation keys: These keys are used for moving around in documents / editing text. They include the arrow keys, HOME, END, PAGE UP, PAGE DOWN, DELETE and INSERT.
# Numeric keypad: The numeric keypad is handy for entering numbers quickly. The keys are grouped together in a block like a conventional calculator or adding machine.
