This very simple extension adds an 'tt' command to the Chrome Omnibox. For example, typing 'tt TTView' will bring up a list of all class names in the Three20 Library API matching 'TTView' — selecting a list item navigates to the relevant Three20 API Reference URL on Install through the Google Chrome Extension Gallery Source code available on GitHub Requires Chrome 9 or later. This is inspired by Roman Nurik's Android SDK Reference Search and The Google Chrome Extensions sample: Extension Docs Search.
