Depending on the task you are carrying out, you want you fingers either in your keyboard or in your mouse; and you want them to stay there. When I am programming I want to forget about my mouse and this implies that I should be able to open new terminals, navigate the code or check Stack Overflow without missing it. On the other hand, when working on my pictures, I want to prescind as much as I can from the keyboard, or at least limit my interaction with it to only one hand. Today I will tell you about the tools I use that allow me to feel comfortable working on my mac; from mapping gestures and shortcuts to choosing the speed of a certain key repetition.
