With the Steam-Version, you can use the Steamoverlay, which offers such a feature on its own (and works in every game, even non-steam-games like Minecraft). So, if you use the steamversion or have steam, add Crysis 2 to the list of non-steam-games, start the game via steam and use the overlay. The default-key is F12, but that can be changed to any key you want.
For the default version without using Steam in any way... I have no idea. I don't think it's even possible as there is nothing like that in the control-options. Of course, you could use the print-key but that only stores one screenshot and you need to add it to paint or something like that and safe it later. Not really suggested.
Or you use a third-party-program - which in the end just ends up doing the same as the Steamoverlay...
