If you have a key fob and have ever been curious about the circle arrow button and its function, here's what it means.

One of four keyboard keys that move the cursor (the pointer on screen) up, down, left and right. See cursor keys. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.

Some benefits of a smaller keyboard are obvious, but I realized that the greatest impact only comes after you've used one for a while. A total game-changer.
