Vimium: Is there a way to bring focus to the Youtube player?

[themaick]

Every time i need to focus on the player to use the Youtube's built-in shortcuts, i have to do it with the mouse. I tried with the "f" command of Vimium but didn't work.

You can use insert mode 'i' to use built in shortcuts j,k.l,f etc. and hit Esc key to return to normal mode. While in full screen mode (i, f), the first Esc exits full screen and second one exits insert mode (check out issue #2963 if this is a problem).
