An HMI application supporting interaction between an operator and runtime control processor information is described herein. The HMI application provides graphical user interface-driven functionality including, among other things supporting a horizontal hierarchical view selection menu. Furthermore, visual alarm indicators associated with the view selection menu guide an operator through each view selection level to a view showing an alarm's source. The horizontal view selection menu is traversable by both a graphical pointer and keyboard strokes (e.g., dynamically assigned function keys). Enhanced faceplate overlays provide access to detailed information from a control block such as alarm limits and tuning parameters. Such detailed information is accessed by first exposing a menu of detailed information, and thereafter rendering the detailed information within a work area of the faceplate separate from the menu from which the detailed information type is selected for the control block.
