Google Chrome Extensions - Set focus to omnibar

I´m developing a Google Chrome Extension which need to set the focus to the Omnibar. I haven´t found anything in the API refe开发者_运维问答rence. Is it possible to do that?

Thanks for your help!

No such API method, plus looks like it is not possible to simulate a keyboard shortcut that puts focus into the ominbox (CTRL+L) as explained here.
