This plug-in provides automatic closing of quotes, parenthesis, brackets, etc., besides some other related features that should make your time in insert mode a little bit easier, like syntax awareness (will not insert the closing delimiter in comments and other configurable regions), and expansions (off by default), and some more.

Most of the features can be modified or disabled permanently, using global variables, or on a FileType basis, using :autocmd.
