Hi Cheryl,
I am Dave, I will help you with this.

Press the Windows Key + Shift + S and that will take a screenshot you can then paste that into any document
You will also find the screenshot on the Clipboard app by pressing the Windows key + V

May I ask, what do you mean you have no print screen key, is it broken?
If it is, you can use a utility like the free SharpKeys or AutoHotKey to remap that key to another key on your keyboard.
