When watching a recorded game, you can use any and all hot keys to check buildings for research, units, etc. Also you can see what control groups they have formed by hitting 1, 2, 3....

Spy units will automatically use the Bribe, and Informer skills when you click on an enemy unit or building, respectively. No need to hit the actual command.

Re: I see double-clicking on idle citizen

will activate all idle citizens. PLEASE tell me we can do this with military units. i remember in Cossacks game where if you click on one unit and press ctrl+Z, it would highlight and activate all units of that type only (ctrl+A would activate all units).

Click a military unit, press "home" to activate all units of that type.

The spacebar also performs this function.
