Defining Keys
4.1 Define Key Editor
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.
Modifier Keys
A modifier key is a key that modifies the behavior of other keys when
it is pressed and held down. Modifier keys are treated as a special
kind of local terminal function. The function modifier keys are:
Shift
,
Ctrl
, and
Alt
.
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.
