Defining Keys

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. For example, pressing an alphanumeric
key in combination with the
Shift
modifier key will normally send the
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.
