Thanks for the information. The feature you have described is not exactly what I was after originally, but it seems like it will probably be useful so I have enabled it.

What I was after was something that actually inserts the closing brackets for you to help ensure the brackets remain matched.

The ParEdit extension that Timur described is exactly what I was after.

You can enable it with something like (show-paren-mode t) in your .emacs. Depending on the Emacs version, there is also an item the "Options" menu. `M-x customize-option show-paren-mode' will also work. In Emcas 23 it's enable by default.

There is also a slightly different feature called "paren blinking" which moves the cursor temporarily back to the opening paren when the closing ) is inserted. That's useful if you work on a black&white terminal.
