Disable Vimium in Chrome w/ shortcut?

Howto disable / enable Vimium in Chrome with simple keyboard shortcut? Trying to avoid using the mouse 🙂

For example, in Vim for Visual studio, the entire Vim can be toggled on/off with Ctrl+Shift-F12, handy in Chrome where some pages have shortcuts, that Vim interfers with.

Pop-up help (‘?’) doesnt helpt.
