For power users, keyboard shortcuts have been introduced in version 1.0.3.
You can now quickly select a User-Agent using numeric keys 1 to 9.
You still have to use the mouse to open the extension popup, but switching will be faster if using the keyboard shortcut.

This is the homepage of the Chrome User-Agent Selector extension.
The extension allows you to modify on a per-tab basis the User-Agent HTTP header sent by Chrome in order to mimic other browsers. You can also add, edit, export and import your own user-agents.
Please note that it currently requires a Chrome 17.x version, available in the Beta Channel : http://www.chromium.org/getting-involved/dev-channel
