If you really want to see the advantage of keyboard hotkeys just look at the top Starcraft players. Yes they still use their mouse but they need hotkeys to even be able to compete at that level. They actually measure the number of actions they can execute per minute! There's no way it can be done only with either just the mouse or keyboard
I think software development also falls into this category. Some hotkeys are at least an order of magnitude faster. And 90% of the time hotkeys will be faster. But in some cases you absolutely need to use your mouse, it's just much faster.
