( runs the command c-electric-paren
which is an interactive compiled Lisp function in `cc-cmds.el'.
It is bound to ), (.
When I am in a cc-mode file it returns:
(c-electric-paren arg)
Insert a parenthesis.
If `c-syntactic-indentation' and `c-electric-flag' are both non-nil,
the
line is reindented unless a numeric arg is supplied, or the
parenthesis
is inserted inside a literal.
Whitespace between a function name and the parenthesis may get added
or
removed; see the variable `c-cleanup-list'.
Also, if `c-electric-flag' and `c-auto-newline' are both non-nil, some
newline cleanups are done if appropriate; see the variable `c-cleanup-
list'.
In the *scratch* buffer it returns:
( runs the command skeleton-pair-insert-maybe
which is an interactive compiled Lisp function in `skeleton.el'.
It is bound to {, [, <, (, ', ".
(skeleton-pair-insert-maybe arg)
Insert the character you type arg times.
With no arg, if `skeleton-pair' is non-nil, pairing can occur. If the
region
is visible the pair is wrapped around it depending on `skeleton-
autowrap'.
Else, if `skeleton-pair-on-word' is non-nil or we are not before or
inside a
word, and if `skeleton-pair-filter-function' returns nil, pairing is
performed.
Pairing is also prohibited if we are right after a quoting character
such as backslash.
If a match is found in `skeleton-pair-alist', that is inserted, else
the defaults are used. These are (), [], {}, <> and `' for the
symmetrical ones, and the same character twice for the others.
