Reply key general purpose input (GPI) functionality on lever key panels

If you connect a footswitch (or other type of switch) to GPI 3, which is pre-assigned to the Reply key, the panel clears the item that is currently being viewed on the reply stack when you release the switch.

You can use the Reply key up/down to scroll through the Reply key stack if more than one call is present on the answerback stack. To move to the next call, press the up button. To return to the previous call, press the down button.
