[Fractint] Defaults

Does anyone know how to set the defaults on specific pages, ie, x, y or z in fractint without going out and back in? For example, when in the middle of creating, actually diddling, with the formulas, I go to another formula and all the settings go with me to the new screen. Is it possible there is some way to reset these pages to their original default values without exiting? Maybe a ctr-x for x, or alt-z for z? I have looked in the documents and couldn't any reference to this procedure. Help, anyone, please? David M Fisher
