I’m old. So old. In my first job, my company at the time gave me one of the very first Windows-based computers in the building — you know, instead of DOS-based. And it was fun. Except they forgot to give (buy) me a mouse. So for two weeks (before Amazon Prime), I had to navigate WINDOWS and all Windows-based programs with just the keyboard. I fly through Excel with the keyboard shortcuts to this day.
