Basic Copy,Cut, Paste how to/printable?

Printable how to of coping, cutting, and pasting using your mouse, can you help? I can’t find a basic printable tutorial page of this function. I have found many how to’s for cutting, copying, and pasting from the file menu. My mother-in-law needs this for a print-out for next to her PC to refer to as she is learning to cut, copy, and pasting. Thank you for your time I and my mother-in-law thanks you.
