Casio HK1223 - Manual (Page 47)

2-4 Operating Your Computer
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. When
the lock keys ( Caps Lock , Num Lk , and Scroll Lk ) are pressed, their
corresponding indicators light up.
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.
