Chrome: Scrolling around with your keyboard in Google Chrome isn’t exactly a nice experience. It’s jerky, and you can’t really read while you do it. Smooth Key Scroll is an extension that makes scrolling with the keyboard as smooth as it is with a mouse.
Smooth Key Scroll essentially ignores your keyboard’s repeat rate to remove the stuttering you usually come across when you scroll with a keyboard. This results in a much smoother keyboard scroll that can be sped up or slowed down using the Alt and Ctrl keys. If you prefer to navigate with a keyboard as opposed to a mouse, Smooth Key Scroll makes that a little more pleasant.
