I was using extensions like Vimium, Saka Key( to use only keyboard to control web browser )
sometimes, I want to leave focus, in the current tab, so that I can active those extensions with keyboard keys
e.g.
1.when cursor focus on an input element, I can press ESC key or move my cursor and click in blank space in this page, then I can press 'f' to active Vimium
2.when cursor focus in the address bar in google chrome, press ESC key just don't work, I don't want to move my cursor, then click, is there any keyboard shortcut to defocus in the address bar?
