Can .change handle immediate text changes?

Can .change handle immediate text changes?

Ok, I am really confused. Everywhere I search, I keep bumping into $(this).change method. I would like an event to fire every time text changes inside <input type="text" /> element. Meaning a user types in a letter, and the even fires immediately. Is .change the wrong thing? Because it seems to fire every time the focus is lost, or gained and the text has been changed. Is there anything that can run as soon as any letter is added/removed from input text?

Thank you.
