My colleagues often comment on how quickly I can do something on a computer. And most of the time I have to admit knowing your way around a computer is useful. Using things like keyboard shortcuts can be very handy. But I can also tell you from personal experience that it is not always a good thing.
Sometimes quick fingers can press send, when you should rather have read that email again.
Sometimes my quick fingers can send the wrong document on Classroom, and cause lots of embarrassment.
So rather take a extra moment and be sure that what you are sending is really what you want to send. Because once it is out there, it is out there and not everything has an undo button.
