With the touchscreen control interfaces that I myself have designed and built (which were for things far less important than nuclear power), there was no paging involved. Everything had a place, and that place was always the same day-to-day (barring infrequent redesigns of some aspect or other, but old-school buttons-and-knobs control panels sometimes see revisions as well as the reality of what they control changes over time).
