I got this new computer game called Greg's World. It's based on old school gaming and it's really cool. I'll put up screenshots of the game as I play.
Hold on, I can't do screenshots.
On Linux, click on the application finder at the top of the shortcuts bar and search for “take screenshot” On Windows:
Step 1: Press Print screen on your keyboard.
Step 2: Open up MS Paint.
Step 3: Go to Edit, and click Paste.
On OS X:
Step 1: Press Command, Shift and 3 at the same time.
Step 2: There should be a file on your desktop called Screenshot (today's date and time).
Did that help?
Then drag the shortcut onto the shortcut bar.
