Re: Can you hold down the power button
My laptop's return key has both a carriage return arrow printed on it, and the letters Enter printed on it.
Of course, carriage return is an old typewriter terminology from when a physical paper carrier would move to the left until the end of the line had been typed, and the operator pressed the key to move the carrier back to the rightmost (margin stopped) position, as well as do a line feed (hence CRLF).
(And before that, a physical lever was used to return the carrier and retension a spring.)
Of course, most computers don't have carriages (or carriers).
