Today is a quick and short one. Wondering how to take a screenshot of just a single application or window? Yes, Apple makes it easy, just kinda hard to remember the exact key strokes 😉
Press Command-Shift-4 then Spacebar
Then move the mouse with the little camera icon over the application window that you want to take a screenshot of. So useful!!
What I learned today 
Thanks! Knew about Command + Shift + 3/4, didn’t know about spacebar. Really helped me out!!!
