Since you are running Microsoft Windows natively, perhaps it may redefine your keyboard to look like a "Windows Keyboard."
Indeed it does redefine the keyboard, but it doesn't add a new one for printscreen, the b*stard!

Apple has long adopted the Cmd+shift+3 for screenshots.
However it appears that some of the top rows of keys on your machine are 14 in number. It accidently appears that on my keyboard, the far right number 14 key on the top row is the "Print Screen" key.
"Esc" key on far left, "Eject" key on far right, 12 "F" keys in the middle.
After looking about a bit on Apple Support, I think that indeed Apple stuff redefines the keyboard, and that the "Apple Logo" keys are important in using the different keyboard layouts.
Sounds important, I'll have a look at that. When pressed, the "Command" or "Apple" key (your Apple Logo key) pops up the Windows "Start" menu.
I am glad to have gained an essential introduction to Apple stuff. I shall never buy an apple product for any reason, but most particularly because someone says it can run Microsoft Windows and is "simpler" than what Microsoft sells. Apple Support has just as much, if not more, garbledook articles about how to sort over the bones of the operating systems than Microsoft does.
We all have our sympathies. I have the same feelings about Microsoft, but I truly believe that the market quota should be inverted.
I mean, people in general should be using MacOS -- a more task-oriented system (just do the stuff you have to do), leaving Windows for the computer-geeks niche, the keyboard-short-cutting-virtuosos niche and the let's-find-a-way-to-work-around-this-obstacle niche.
Now that I'm using both systems at the same time, I came to the conclusion that 85% of the personal-computer market is actually buying a bad product.

Now, what about that print screen shortcut key

Does anyone knows one, or I'll have to download some freeware?
