For anybody who is looking for the way to make a screenshot now :
Before, this was possible by tapping the dedicated button on the bottom of the street.
I regret that this button has dissapeared in the new version.
However : in Jelly Bean, it can be done by pressing the ON/OFF-button and the VOLUME DOWN button simultaneously. Exactly together at the same time, cause the machine is not forgiving on this point.
Good luck !
