Control List Selector with Enter

The Control List Selector with Enter object allows the operator to choose
from items in a list. As the operator presses the Up Cursor and Down
Cursor buttons, an arrow indicator moves up and down through the list,
wrapping around the top and bottom of the list. The item is not actually
selected until the Enter button is pressed; the selected item highlights in
reverse video and the PLC input is updated to reflect the new state.

The states, therefore, are not necessarily executed consecutively. Rather the
new state is determined by the position in the Selector when the Enter
button is pressed.
