What is the autocomplete function in questions?

The autocomplete function in questions helps you type questions faster by providing you with recommendations of questions while you write. The system tries to understand what is the most likely question you are trying to ask at this precise moment and offers you a recommendation.

If the question you want to ask is been recommended, simply click on it instead of having to type it by yourself. It is a faster way to help you write and send a question to someone else
