Instead of maximizing, minimizing, or having to move apps around manually, you can quickly switch between apps without moving windows around.
On your Mac, do any of the following
Switch to the previous app: Press Command-Tab
Scroll through all open apps: Press and hold the Command key, press the Tab key, then press the Left or Right arrow key until you get to the app you want - then, release the Command key
If you change your mind while scrolling through the apps and don't want to switch apps, press Esc or the Period key, then release the Command key.
