I see that sometimes when I press it, it automatically changes the TOC without asking what I want it to do. Now it's not giving me an option at all. It's just automatically updating the entire TOC, and thus removing quite a bit of manual work I had to do on this long TOC. I added a header and thus increased the size of the header. This changed the page numbers a little, and all I want to do is update that, but I no longer appear to have this option. Is there a way to turn this on and off? Thanks.
