auctex: Customizing

 
 1.2.8 Customizing
 -----------------
 
 Most of the site-specific customization should already have happened
 during configuration of AUCTeX.  Any further customization can be done
 with customization buffers directly in Emacs.  Just type 'M-x
 customize-group RET AUCTeX RET' to open the customization group for
 AUCTeX or use the menu entries provided in the mode menus.  Editing the
 file 'tex-site.el' as suggested in former versions of AUCTeX should not
 be done anymore because the installation routine will overwrite those
 changes.
 
    You might check some variables with a special significance.  They are
 accessible directly by typing 'M-x customize-variable RET <variable>
 RET'.
 
  -- User Option: TeX-macro-global
      Directories containing the site's TeX style files.
 
    Normally, AUCTeX will only allow you to complete macros and
 environments which are built-in, specified in AUCTeX style files or
 defined by yourself.  If you issue the 'M-x TeX-auto-generate-global'
 command after loading AUCTeX, you will be able to complete on all macros
 available in the standard style files used by your document.  To do
 this, you must set this variable to a list of directories where the
 standard style files are located.  The directories will be searched
 recursively, so there is no reason to list subdirectories explicitly.
 Automatic configuration will already have set the variable for you if it
 could use the program 'kpsewhich'.  In this case you normally don't have
 to alter anything.
