If you're using formfields, checking each one's 'calculate on exit' property will achieve the desired result - without the need for Ctrl-A, F9 - except for the Table of Contents & Table of Figures. There is a convoluted workaround for those, too, however. That workaround involves putting each them at the end of the document, inside SET fields and, at where you want the Table of Contents & Table of Figures to appear, inserting a cross-reference to the relevant SET field's bookmark.
