 2.5 Entering Mathematics
 ========================
 
 TeX is written by a mathematician, and has always contained good support
 for formatting mathematical text.  AUCTeX supports this tradition, by
 offering a special minor mode for entering text with many mathematical
 symbols.  You can enter this mode by typing 'C-c ~'.
 
  -- Command: LaTeX-math-mode
      ('C-c ~') Toggle LaTeX Math mode.  This is a minor mode rebinding
      the key 'LaTeX-math-abbrev-prefix' to allow easy typing of
      mathematical symbols.  '`' will read a character from the keyboard,
      and insert the symbol as specified in 'LaTeX-math-default' and
      'LaTeX-math-list'.  If given a prefix argument, the symbol will be
      surrounded by dollar signs.
 
    You can use another prefix key (instead of '`') by setting the
 variable 'LaTeX-math-abbrev-prefix'.
 
    To enable LaTeX Math mode by default, add the following in your
 '.emacs' file:
      (add-hook 'LaTeX-mode-hook 'LaTeX-math-mode)
 
  -- User Option: LaTeX-math-abbrev-prefix
      A string containing the prefix of 'LaTeX-math-mode' commands; This
      value defaults to '`'.
 
      The string has to be a key or key sequence in a format understood
      by the 'kbd' macro.  This corresponds to the syntax usually used in
      the manuals for Emacs Emacs Lisp.
 
    The variable 'LaTeX-math-list' allows you to add your own mappings.
 
  -- User Option: LaTeX-math-list
      A list containing user-defined keys and commands to be used in
      LaTeX Math mode.  Each entry should be a list of two to four
      elements.
 
      First, the key to be used after 'LaTeX-math-abbrev-prefix' for
      macro insertion.  If it is nil, the symbol has no associated
      keystroke (it is available in the menu, though).
 
      Second, a string representing the name of the macro (without a
      leading backslash.)
 
      Third, a string representing the name of a submenu the command
      should be added to.  Use a list of strings in case of nested menus.
 
      Fourth, the position of a Unicode character to be displayed in the
      menu alongside the macro name.  This is an integer value.
 
  -- User Option: LaTeX-math-menu-unicode
      Whether the LaTeX menu should try using Unicode for effect.  Your
      Emacs built must be able to display include Unicode characters in
      menus for this feature.
 
    AUCTeX's reference card 'tex-ref.tex' includes a list of all math
 mode commands.
 
    AUCTeX can help you write subscripts and superscripts in math
 constructs by automatically inserting a pair of braces after typing <_>
 or <^> respectively and putting point between the braces.  In order to
 enable this feature, set the variable 'TeX-electric-sub-and-superscript'
 to a non-nil value.
 
  -- User Option: TeX-electric-sub-and-superscript
      If non-nil, insert braces after typing <^> and <_> in math mode.
 
    You can automatically turn off input methods, used to input non-ascii
 characters, when you begin to enter math constructs.
 
  -- User Option: TeX-math-input-method-off-regexp
      Input method matching this regular expression is turned off when
      '$' is typed to begin math mode or a math environment is inserted
      by 'C-c C-e' ('LaTeX-environment').
