Today while I was trouble shooting with another teacher, I came across a keyboard shortcut that I didn’t know about. It’s ⌘ H. You can use it to hide the app you would normally minimize. For example, if you are working in Firefox, but want to put it aside to work in Word, just click ⌘ H. Firefox will now vanish. When you want it again, just click on the icon in the dock or you can use ⌘ TAB. Hold down ⌘ TAB to bring up your open apps and then while holding down ⌘, click the TAB button to select which app you want. You can watch this video to demonstrate.
