Karabiner-Elements is a simple app that allows you to re-assign keys from one position to another on your keyboard.
This can be particularly helpful if you wish to convert a Windows keyboard to Mac. Some of the key positions are different, but they can simply be changed using Karabiner-Elements. You can also move obscure key strokes to something you find easier to remember & use, increasing your productivity.
