Transition from a traditional keyboard to a MX Keys S keyboard

I just purchased a MX Keys S keyboard. I like the feel and touch, but I am not used to this type of keyboard. I have been using a traditional keyboard for a long time with keys that did not need explanation (i.e. numbers lock, scroll lock, print screen, etc.). This new keyboard has nothing that I can relate to in performing any of the mentioned functions. I had the keyboard installed without any further guidance or instructions. So I did not set it up. I am not a techie by any means, so is there anyone who can help me make the transition from a traditional keyboard to this new one? All help would be appreciated. Thank you.
