One of the most powerful aspects of Google Chrome is the omnibox, also known as the address bar. You can type URLs and searches into one unified place and it all just works. With the new omnibox API, extension developers can make the omnibox even more powerful.
The omnibox API lets extension developers add their own keyword command to the omnibox. When the user types a query prefixed by this keyword, the extension can suggest potential completions and react to the user's input.
For example, this extension "Switch to Tab" allows you to quickly search your open tabs and switch between them using Chrome's omnibox.
Enter "sw<tab>" followed by a search term to begin using Switch to Tab. You can enter multiple keywords separated by space.
Upon pressing enter, the extension will select the first match and switch to that tab, so one need not type press down if the first match is desired.
