For screen shots, if you have a windows laptop, there should be a button somewhere that has "PRTSC" or "PRT SCR" on it. Click that when you want to take a screenshot (you may want to press the FN key and then click that button depending on the computer).
For screen recording though, you will need a separate program. If you want to record this game, you will need to take it off full screen, there is an option to do that when you start it up and it shows up when the rendering selector shows up. You can either switch rendering modes, or if both are in full screen mode, you can click on the full screen and switch it to "No."
