When I turn on "Single Player Auto End Turn" in the game options I don't have to hit enter to move to the next turn. Trouble is the game can run on auto for quite a lot of turns (esp. on "marathon").
Sometimes an "exploring" unit finds something and I want to tweak the course that has been set, but I'm powerless until the next user event. Is there some way I can cut in and get control back? A keyboard shortcut? It's not "esc".
