I forgot to add a possibly important piece of evidence. The changes I made to the .tex file do not show up when I compile—I get the old version, not the new one, even
<div class="">after several compilations.<br class="">

All of a sudden, some of the links between files in the TS editor have broken.
<div class="">I have a book project involving a master file (Coeur.tex) and many chapter files linked to the main one with the "<span style="font-size: 12px;" class="">% !TEX root =</span><span style="font-size: 12px;" class="">
</span><font size="3" class="">Coeur.tex” line at the start of each chapter file.</font></div>
<div class=""><font size="3" class="">That linkage works fine for compiling the book. Toggling between .tex and pdf (ie, \command-1) works as well.</font></div>
<div class=""><font size="3" class="">However, if I try to go between a phrase in a .tex file and the corresponding phrase in the .pdf (or vice-versa) via command-click, nothing happens.</font></div>
<div class=""><font size="3" class=""><br class="">
</font></div>
<div class=""><font size="3" class="">I tried quitting and restarting TexShop, to no avail.</font></div>
<div class=""><font size="3" class="">I also pulled up an old file (differnt project) with a similar configuration. On one try, I could go from pdf to tex, but not the other way.</font></div>
<div class=""><font size="3" class=""><br class="">
</font></div>
<div class=""><font size="3" class="">Immediately before this happened, I was using command-F to search for and modify certain words in the text.</font></div>
<div class=""><font size="3" class=""><br class="">
</font></div>
<div class=""><font size="3" class="">I suspect this is an Apple problem rather than TS as such, though it is when using the TS editor that I encounter it.</font></div>
<div class=""><font size="3" class=""><br class="">
</font></div>
<div class=""><font size="3" class="">Any suggestions for a fix?</font></div>
