Hi Idle may be a two position switch on the dash/control panel. Unless you have a separate digital tach with buttons on it. As I recall, the '96+ ambulances I used to drive for an ambulance company that shall remain nameless to protect the innocent, had a separate Ford digital tach that had the high idle controls on it.
