Scrprint and paste in Word

Hello all, can anyone help? i do expert ECDL, teach adult ed and use ScreenPrint and Pasting into MS Word quite a lot. My father just got me a new Macbook Pro and i cannot find out how to easily do this. it has taken me almost and hr, i am fed up now and need help. i just want a shortcut to copy screen and paste it into Word for editing into a report. Basically just copy + paste. so far i think i have managed a scrprt on desktop which is useless.

Can anyone help? i hate to say this but i miss the scrprt button and crl V option in windows, it was so much easier.

thanks
