How to Take Screenshots
From Legacy Roblox Wiki
Since ROBLOX can only run on Windows, I'm guessing you're not using a Mac.
Most non-Macs have a button called "Print Screen" on their keyboard that should say "PrtSc"
When you press this button, what you see on screen will get copied to the clipboard. Now simply open any picture-editing software, and "Paste" The picture in using Ctrl+V. Now you can save the picture, or edit it however you want.
