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.
