Have you ever wondered if your keyboard shortcuts are set up optimally? Well, I did, so I decided to visualize it with a heat-map.
It proved to me that I rely on my left pinky too much, so I’ll try to rework my shortcuts.
You can check out the project here, currently it only works on Linux.
I’m not sure if it’s directly mapping the input. I think it’s getting the other keys input and binding it to the same commands. Also, Emacs was around even before the X windowing system, so they probably came up with the mappings before a lot of these common defaults came about.
