I think it's related to the mouse because the mouse is often used with some type of GUI, and a GUI doesn't allow you to automate the stuff you shouldn't care about very well. Especially when you deal with text all the time. There are solution for that though, but I find them less convincing than the tools we have using our keyboard. So it's linked, but I agree that maybe this question of mouse / keyboard is not the central one.
