Question: Switching between Computer/ Human Control

[whdonnelly]

Does anyone know how to switch between computer and human control during an ongoing game?
I asked because my dog somehow switched my units to computer control while while i was away from the keyboard. She will not tell me what keys she used.
This is 40 turns into a game, so I would prefer to recover where I'm at. So far the game guide or forums aren't returning anything that works.

Thanks,

Will
