I have to disagree with the Windows key being useless. Win+Shift+S for selective screen grab to clipboard. Win+E to open a new Explorer window. Win+D to show the desktop. They were my go-tos. Now I’m forced to use Mac I use the Win key all the time too, Win+C, Win+V…
If anyone genuinely feels this way and wants to get started in coding, I highly recommend doing one of the mooc.fi courses. Codecademy is fine as a taster/refresh but don’t waste money on the premium when something like mooc is available for free.
