Using the Keyboard
Your keyboard has all the standard functions of a full-sized computer
keyboard plus a Fn. key added for specific functions.
The standard functions of the keyboard can be further divided into four
major categories:
Typewriter keys
Cursor-control keys
Numeric keys
Function keys
Typewriter Keys
Typewriter keys are similar to the keys on a typewriter. Several keys are
added such as the Ctrl, Alt, Esc, and lock keys for special purposes. The
Control key is normally used in combination with other keys for
program-specific functions. The Alternate key is normally used in
combination with other keys for program-specific functions. The Escape
key is usually used for stopping a process. Examples are exiting a
program and canceling a command. The function depends on the
program you are using. When the lock keys (Caps Lock, Num Lk, and Scroll
Lk) are pressed, their corresponding indicators light up on the
computer’s device indicators.
Cursor-Control Keys
NOTE: The word “cursor” refers to the indicator on the screen that lets you know
exactly where on your screen anything you type will appear. It can take the form of a
vertical or horizontal line, a block, or one of many other shapes.
