;;; Simple BibTeX mode for GNU Emacs
;;; Bengt Martensson 87-06-28
;;; changes by Marc Shapiro shapiro@inria.inria.fr 15-oct-1986
;;;  (align long lines nicely; C-c C-o checks for the "OPT" string;
;;;   TAB goes to the end of the string; use lower case; use
;;;   run-hooks)
;;; Marc Shapiro 19-oct-1987
;;;  add X window menu option; bug fixes. TAB, LFD, C-c " and C-c C-o now
;;;  behave consistently; deletion never occurs blindly.
;;; Marc Shapiro 3-nov-87
;;;  addition for France: DEAthesis
;;; Skip Montanaro <steinmetz!sprite!montanaro> 7-dec-87, Shapiro 10-dec-87
;;;  before inserting an entry, make sure we are outside of a bib entry
;;; Marc Shapiro 14-dec-87
;;;  Cosmetic fixes.  Fixed small bug in bibtex-move-outside-of-entry.

;;; NOTE by Marc Shapiro, 14-dec-87:
;;; (bibtex-x-environment) binds an X menu for bibtex mode to x-button-c-right.
;;; Trouble is, in Emacs 18.44 you can't have a mode-specific mouse binding,
;;; so it will remain active in all windows.  Yuck!

;;; Bengt Martensson 88-05-06:
;;; Added Sun menu support.  Locally bound to right mouse button in 
;;; bibtex-mode.  Emacs 18.49 allows local mouse bindings!!
;;; Commented out vtxxx-keys and DEAthesis.  Changed documentation slightly.

  "Major mode for editing bibtex files.  Commands:
\\{bibtex-mode-map}

A command such as \\[bibtex-Book] will outline the fields for a BibTeX
book entry.

The optional fields are preceded by ""OPT"", thus ignored by BibTeX.
Use \\[bibtex-remove-opt] to remove ""OPT"" on the current line.

Use \\[bibtex-find-it] to position the dot at the end of the string on the same line.
Use \\[bibtex-next-position] to move to the next position to fill in.  Use \\[kill-current-line]
to kill the whole line.

M-x bibtex-x-environment binds a mode-specific X menu to control+right
mouse button.

mouse button.
