I play Civ V on my Mac in my rare free time but I'd like to reduce my mouse use. I have found numerous charts with keyboard shortcuts for exotic actions, but cannot find anything on how to do many basic actions. For example, the key for move is M. So if I press M, I can use the arrow keys to select a potential location to move to. But how do I get the unit to actually go there?? (I've tried Return, Enter, Space, pressing M again, pressing CTRL-M...)

Likewise, every few moves Civilizations wants me to make a decision on something, for example, a social policy or research direction. But I can't find any way to even bring up that screen with the keyboard, much less choose an option, even though Civ has a centralized flashing message bar just begging for a keyboard-shortcut to activate.
