This is a terminology misunderstanding.
() parentheses
[] brackets
{} braces
You want completion for parentheses, not braces. Parentheses are not
syntactic entities in LaTeX (pstricks notwithstanding). You may want to
look at the generic key sequence:
M-( runs the command insert-parentheses (found in global-map), which
is an interactive byte-compiled Lisp function in ‘lisp.el’.
It is bound to M-(.
(insert-parentheses &optional ARG)
Enclose following ARG sexps in parentheses.
Leave point after open-paren.
A negative ARG encloses the preceding ARG sexps instead.
No argument is equivalent to zero: just insert ‘()’ and leave point between.
If ‘parens-require-spaces’ is non-nil, this command also inserts a space
before and after, depending on the surrounding characters.
If region is active, insert enclosing characters at region boundaries.
This command assumes point is not in a string or comment.
