Just click and hold the small Application icon at the top of the window of the (saved) document you are in until the small icon goes a little translucent. When you are in a document/image, you can open it in another app, paste it into a message, or store it in a different folder easily.

But did you know you can navigate using Control-right, or Control-left to cycle through them? You don’t even need to use a trackpad or mouse. Spaces - Apple’s useful way of creating different desktop spaces for different uses - can help you stay focused. Just release command when that application is selected.

Keep the command button depressed and tap tab or use the forward or back arrows to navigate to the application you want to use.

A bar appears on your display with all your open apps. Tap Command-tab to open the application switcher. I assume many Mac users know this already, but it’s useful all the same. All windows for that application will be immediately hidden and you can explore the other items on your screen. To do so, Option-click any visible remaining section of Desktop you can see while in the program you want to push out the way. When you have so many windows for a single application open that you can’t get to the rest of your stuff, you can regain that sense of desktop space.

Now, let’s get to some tips you may not have encountered yet.
