How to take a screenshot.

If you want to take a screenshot of your Candy Crush Game

this is the way to do it providing you have a "PrtSc" key.

Press the print screen key on your keyboard.

It may be labelled "prtSc" or similar.

Open an image editing program, such as Paint.

Go to the edit menu and choose "paste".
Now you can save the image or crop it.

Use your crop tool to crop out unneeded parts of the picture.

Go to the file menu and choose "save as"

Navigate to the folder where you want to save the image and 

type a file name for the image.

Select a file type and click the save button.

If your laptop does not have the PrtSc key.

You can use the Fn key

This key is located lower left of your keyboard.

Press and hold the Fn key and press the "Ins" key

which is usually just above the backspace key.

This saves the screenshot to your clipboard.

Next go to your editing program (paint) and follow the steps 

outlined above from "paste".
