I am trying to play CIV II only with keyboard, but I don't know all the keyboard shortcuts and there's also an occasion when you can't use the keyboard:

When a window pops up telling me that city X has built an aquaduct (or whatever), I can zoom to the city.

But when I want to (C)hange production, I cannot use the "C"-button on my keyboard, because in the background, the game is still in "moving units"-mode.
A window pops up telling me that I'll have to close the city-window first.

On the other hand, when I'm in "viewing pieces"-mode, and I "enter" on a square with a city, I CAN use the keyboard:

"c" for changing production
"b" for rush buy...

Who knows how I can still use the keyboard, even when I use the "zoom to city"-feature (or: How can I make the city-window become active?)?

And who knows shortcut keys for:

selling items, change resources in resource window of a city window, change "Elvis" into Tax or Science, and so on....
