Is there a way to let emacs automatically search and replace strings/regex in all files that are part of a multifile document? With C-s or M-% only the current buffer is included in the search, even if TeX-master variable is set.

I'm using GNU Emacs 24.3.1

    classic way is to use tags-query-replace (with etags) Oct 25, 2014 at 11:54
  • What version of Emacs are you using?

    Enable reftex, it contains features to search and replace (I think it is based on David's answer). Always pair auctex with reftex. Makes your life easier

    @daleif That's it: reftex-query-replace-document and reftex-search-document. Please add it as solution so I can accept it. Oct 25, 2014 at 14:31

When ever you use emacs and auctex always remember to enable reftex as well or you will miss out on all sorts of useful goodies. In this case reftex-query-replace-document and reftex-search-document. Another one I like is the label rename feature, really nice.

    In addition, reftex-isearch-minor-mode lets you use normal C-s key stroke to search the whole multifile document. thanks! Oct 25, 2014 at 17:12
  • @S1lentSt0rm Wow, I never knew I missed this!
