AutoPairs is a free extension that helps you type parentheses, brackets, and braces. When you type a left brace, for example, AutoPairs automatically types a right brace and a left arrow, so that you are instantly ready to type what goes between the braces. AutoPairs should run on any PowerMac that uses an OS version less than 10.
New in version 1.1: When the title of the front window ends with ".html", ".htm", or ".xml", AutoPairs similarly pairs the less-than and greater-than signs, also known as angle brackets.
New in version 1.2: Double quotes, both curly and straight kinds, are now paired. More file extensions trigger angle bracket pairing: ".php", ".php3", ".dtd", and ".xsl".
