You will have to provide further information. This works fine for me. Things to try/check:
- Make sure
reftex-mode is actually on. Your minibuffer/status line thing should say something like
(LaTeX/MP Ref Abbrev)
- Try refreshing the window: type r when in the
C-c = window.
- Add things to the variable
reftex-include-file-commands (which is the variable which lists the commands reftex looks for when working out what other files to scrape TOC information from).
- Go to the inputted file and type
C-c = there. Then go back to the main file to see if that's made a difference.
- Make sure the files contain some
\section commands or similar, since they are the kind of things that show up in the TOC.
To add a new input command to the
reftex-include-file-commands variable, type:
M-x customize-variable RET reftex-include-file-commands. Something like this should appear:
move the cursor to INS so an empty line shows up and type the name of the input command there. for example, I have added
schminput to my command list. Now, if I had
\let\schminput\input in my
.tex file, reftex would know to search
schminput-ed files for TOC info.
