I'm just beginning with this terrific game.

One of the things I am maybe missing or not understanding is how to best de-select units after issuing orders/commands. I usually right-click, but ZK maps that for many actions. Left click works sometimes, but other times, like after issuing a move command, the selected unit(s) simply move to the click point.

I keep messing up, and I know I have to be missing something.

EDIT: I searched and found a few topics that mention that the ZK command structure requires this unexpected setup, which I can understand, just, how can I be sure to de-select the unit(s)?
