— User Option: reftex-plug-into-AUCTeX

Plug-in flags for AUCTeX interface. This variable is a list of 5 boolean flags. When a flag is non-nil, RefTeX will

          - supply labels in new sections and environments  (flag 1)
          - supply arguments for macros like \label         (flag 2)
          - supply arguments for macros like \ref           (flag 3)
          - supply arguments for macros like \cite          (flag 4)
          - supply arguments for macros like \index         (flag 5)

You may also set the variable itself to t or nil in order to turn all options on or off, respectively.
Supplying labels in new sections and environments applies when creating sections with C-c C-s and environments with C-c C-e.
Supplying macro arguments applies when you insert such a macro interactively with C-c <RET>.
See the AUCTeX documentation for more information.
