Emacs - RefTeX

RefTeX is a Emacs package dedicated for label, reference, citation, and index related operations in \LaTeX. What is exciting, RefTeX has been integrated into Emacs since version 20.2.

RefTeX is easy to use by providing 4 macros, \label, \ref, \cite, and \index. It can be configured as follows.

• Loading the package

  (require 'reftex)
  

• Turning on the mode

  (add-hook 'LaTeX-mode-hook 'turn-on-reftex); with AUCTeX LaTeX mode
  (add-hook 'latex-mode-hook 'turn-on-reftex); with Emacs latex mode
  

• Integrating with AUCTeX

  (setq reftex-plug-into-AUCTeX t)
  

Targeting for quick operations, following keybindings are binded by default.
