If like me, you take the name Windows seriously and frequently have multiple open windows, you’ll like this quick keyboard shortcut for switching between them.
Just hold down the Alt key and press the Tab Key.
This screen will pop up.
Just keep pressing the Tab key to move between windows. Release the keyboard when you land on the window you want to go full screen.
Pretty easy!
The above allows the user to move from window to window from left to right. I use it constantly.
I also use holding down the Alt and Shift keys when tabbing, which allows moving from right to left.
