When you need to express the idea of doing something quickly or efficiently, "zip through" is a great colloquial expression. However, there are several synonyms that can be used to convey the same sense of expedience. For example, you could say "fly through," "blaze through," or "whip through" to indicate that you're moving quickly and purposefully. Similarly, you might use "race through," "burst through," or "dash through" when you want to emphasize the speed of your actions. All of these synonyms convey a sense of urgency, efficiency, and effectiveness, making them effective ways to describe a task that's been completed quickly and with great success.
