Description

I have added a section to the official documentation under Customize/Deepdives/Autocomplete, specifically in the 'How to turn off autocomplete' part, as it was missing information on how to enable/disable autocomplete using keyboard shortcuts.
Initially, I was going to develop a feature to control autocomplete with a shortcut, but I discovered that this functionality already exists.
I believe adding this information to the documentation will help more users utilize the feature more easily.
