Function Keys

Function keys are used to transmit function key sequences or to perform local terminal functions such as the arrow keys (
, , , ), the Shift modifier key, or the key that calls up the Set-Up menu (F3). A User Defined Key (UDK) is a special function key.

A modifier key is a key that modifies the behavior of other keys when it is pressed and held down. For example, pressing an alphanumeric

key in combination with the		modifier key will normally send the
	Shift
shifted or uppercase characters				￿
	for that key.
Modifier keys are treated as a special kind of local terminal function.

The function modifier keys are: Shift , Ctrl , and Alt . Alphanumeric keys can also be modified by pressing Group Shift ( Alt Gr on enhanced PC keyboards) and Alt Shift (Shift-2). Modifier keys themselves cannot normally be modified by other keys. A key assigned to act as the Shift modifier, for example, cannot transmit a function sequence when pressed in combination with the Alt key. Defining a key as a modifier key makes all assignable combinations of that key act as a modifier. Example: Changing the <x key to delete when unshifted and to backspace when shifted.
