Change chrome search engine with keyboard shortcut or programmatically

Is there a way to change the chrome search engine using a keyboard shortcut? E.g. I’m using duckduckgo, and I want to switch to google search for a time, so I would press a shortcut, use google for a while as my default search engine, and press the shortcut to switch back to duckduckgo. (I know about the omnikey search thing, but that’s not what I’m looking for because I would have to append “g” or “!g” to every search.)

If there’s no way to switch using a keyboard shortcut, then is there a way using the Chrome API? I would be willing to write an extension to set this up.
