So if a preference for keyboard-based text editors implies "low mouse skills," wouldn't it be logical to assume that you prefer mice due to low keyboard skills?
You need a keyboard to write code. You don't need a mouse. Keyboards are optimized for two hands. So why use one? If a mouse is such an enhancement, why not use two? Why not have pedal mice for your feet so you can have four mice? The answer is because one mouse is barely necessary as is, hence, keyboard-based text editors are superior.
