Feature Request: Keyboard command to focus search bar

[CubeOfCheese]

I like the new look of the tab page with the search bar front and center. But when I open a new tab, the browser's url bar is already focused. In order to use tab for a cause's search bar I have to click on it first. I'd be much more likely to use it if I could use a keyboard shortcut to focus it. A common one is command + K.
If you point me in the right direction I could try my hand at implementing and opening a PR.

Thanks for the issue! I like this suggestion, but I'm not sure it's possible on the new tab page, because the browser's URL bar has keyboard focus. From Chrome extension docs: "Don't rely on the page having the keyboard focus. The address bar always gets the focus first when the user creates a new tab."

I haven't tested this out, though. You could give it a try with a local extension pointing to a local app. For keyboard logic, a package like Mousetrap would help.
