Look Ahead Preview Mode
If no Key Preview is active, the Key PVW button will not be lit. If it is pressed, the
Color Preview will be switched on and the Key PVW button will be lit. Pressing this
button once more switches on the the BlackWhite Preview and the button will still
be lit. Pressing the button again switches off the Preview (no Key Preview for this
M/E will be active anymore) and the lamp in the button will go out.
It is always the Key Preview for the actually delegated keyer which is switched.
When re-delegating to another keyer, a possibly active preview of the previously
delegated keyer will be switched off. The preview of the newly delegated keyer will
also be switched of. When delegating to the same keyer (i.e. to that one which is
already active), nothing will happen, i.e. the preview state (Off, Color, BlackWhite)
is not changed.
