Documentation
Math mode delimiters inserted by TeX-insert-dollar.
If non-nil, TeX-insert-dollar will insert symbols for opening and
closing inline equation and put the point between them. If there is an
active region, TeX-insert-dollar will put around it symbols for
opening and closing inline equation and keep the region active, with
point after closing symbol. If you press $ again, you can toggle
between inline equation, display equation, and no equation.
If nil, TeX-insert-dollar will simply insert "$" at point,
this is the default.
If non-nil, this variable is a cons cell whose CAR is the string to insert before point, the CDR is the string to insert after point. You can choose between "$...$" and "\\(...\\)".
