What is another word for in an instant?
Pronunciation: [ɪn ɐn ˈɪnstənt] (IPA) 
When something happens quickly, it is often described as happening "in an instant." However, there are plenty of synonyms that can be used to convey this same sense of immediacy and speed. For example, an event could occur "in a flash," "in a heartbeat," or "in the blink of an eye." Similarly, it might happen "in a split second," "in a jiffy," or "in no time at all." These phrases all convey the sense that something happened very quickly or suddenly and can be useful alternatives to the more traditional phrase "in an instant".
