Many of us always thought that the “Windows Key” on the keyboard was just a nuisance. It was just the thing I accidently hit once in a while and the darn start menu would pop-up. But what turns out in reality is that the “Windows Key” has many useful functions.
When used in combination with other keys, here’s what you can do
Windows Key + Tab: Cycles through the buttons in the task bar
Windows Key + D : Minimize or Restore all windows.
