At the bottom of the screen, there is a pile of gold, city, etc. displaying your current
stats. If you click on these, strange things happen, most commonly the following:
After moving or using one of your units, it merely reselects that unit usually. If you
haven't selected any units yet, and you get an enemy army, it will sometimes (about
15%-25%) select the enemy unit for you to control (including neutrals, though you can't do
much with them) For the remainder of the times (I'm not sure what you have to do- just
experiment), it has done other strange things, such as inverting the screen colors,
showing where enemy units are in the black area, and giving phantom Strength 39, Movement
18 Centurions (no matter what army set). Some other things may happen- I've been playing
around with it for a while now.
Note: doing this has occasionally locked up my computer.
