Single post in Basic PC Screenshot Guide

Might want to add: on several laptops (my laptop included in this; not sure if there are some desktop computers that require this as well) you need to click Fn+PrtSc in order to screenshot, or Fn+Alt+PrtSc for just your active window. Suggesting adding this since it took me a week to figure that out on my new laptop and I thought my screenshot button was broken or something, oopsies
