Yoga laptop screenshot?

For an SS do I have to press Ctrl + Alt and Print all at the same time or all in a row?

Logical would be consecutive, since the keys are far apart, which is why it is difficult to press them all at the same time.

I just had the same problem and didn't know how to take a screenshot. I just downloaded Lightshot for that. And whenever I press "Print S-Abf" I can take a screenshot of the screen. You can also edit your screenshot (make it smaller, paint on it, write, share, save it only briefly or save it completely in the folder)

Best you can do.
Is all computers at work "pre-installed"

For that I have a program called Greenshot
