Operation
The previous chart shows that the left Shift key performs the standard
shift functions; while the right Shift key, when used with the dual function
keys (Arrow Keys, Num Lock, and Delete) selects the upper functions
of those keys. That way, both the shifted and unshifted functions of those
keys can be generated.
Because of the multitude of tasks your computer can do, some keys per
form a variety of tasks. There are also a few keys that are unique to
this computer.
The computer keyboard has two major blocks of keys: the function keys/
Icon block and the typewriter block. (Icon is a symbol that represents
an object or concept.) The typewriter block contains alphanumeric keys,
modifier keys, program keys, and other special keys.

Every key on the keyboard has auto-repeat; that is, it repeats itself as
long as you hold it down. This is most useful with keys that move the
cursor, like DEL, RETURN, the space bar, and the arrow keys.
