I narrowed down the problem to LaTeX-outline-name which gives the wrong answer in two situations: 1. If the section (or subsection, etc.) title is very long, namely, if it ends in a column greater than fill-column plus 10, then LaTeX-outline-name reports the title as the first 20 characters in the line. This is particularly ugly since it means the title will start with "\section{" or somehting like that. 2. If the title contains a right brace, LaTeX-outline-name reports the title as ending at that brace. This small document illustrates both problems: \documentclass{article} \begin{document} \section{A title so utterly long that it exceeds the fill column by more than ten characters} \section{Braces \emph{screw} this one up} \end{document} If fill-column is set to a reasonable value, the first section is too long and gets listed in imenu as "\section{A title so ". The second one gets truncated at the right brace: "\section{Braces \emph{screw". The builtin tex-mode uses forward-sexp to allow balanced braces inside the section titles. In my personal configuration I've replace LaTeX-outline-name with: (defun LaTeX-outline-name () "Guess a name for the current header line." (save-excursion (search-forward "{" nil t) (let ((beg (point))) (forward-char -1) (condition-case nil (progn (forward-sexp 1) (forward-char -1)) (error (forward-sentence 1))) (buffer-substring beg (point))))) This attempts to skip over the title using forward-sexp and in case of error uses forward-sentence instead. It seems to work on the files I noticed had a problem before, but I haven't done extensive testing.
