Is C::B usable without a mouse?

[DrewBoo]

Many programmers like environments where you can perform all tasks using only the keyboard.

It seems that C::B is very usable with just a keyboard, however I haven't found a way to set focus on the various windows within the C::B IDE.

Is there a way to cycle focus through the various open C::B windows?  Or to set focus to a particular one?

I see that there's "Focus Editor" in the view menu, but that seems to be a special case specifically for that one window.
