Fighting your tools interrupts thought. A keyboard is a discrete mechanism: you can make mistakes using hotkeys, but the overall state space is infinitely small

Fighting your tools interrupts thought. A keyboard is a discrete mechanism: you can make mistakes using hotkeys, but the overall state space is infinitely smaller than the continuous state space of a mouse. That makes precision easier, which leads to a closer mapping between intent and action, which makes it easier to enter and maintain a flow state.
