Shortcut to turn off autocomplete suggestions

Normally I like the autocomplete suggestions when typing in the address bar. That said, there are also times where I am sharing my screen or showing someone something and I don’t really want them seeing my history pop up. Presently, the only way to disable autocomplete is to go to settings or keep it turned off. I propose a simple shortcut or way to quickly, discreetly, and temporarily disable (and reenable) autocomplete.
