***A way to "mark" armies that should do something on the next turn (e.g if I am sending an army back to its home province for retraining, I often forget to move on the way and it ends up taking YEARS to get back. I tried positioning it on a particular place in a province, but the computer does not save the exact spot from turn to turn.)
You can actually do this Afrit. Take an army or naval unit and place it where you whant it to be in an province or seazone then left-click on this province/ seazone. In 90% your unit will then be in that exact location the next turn. One exception though, if you build a unit or ship in that square your "placed" unit will automatically be moved to the default location.
I find this technique very useful when I´m moving units back and forth through my realm or setting up a shiplink when there´s alot of other vessels in the seas. Usually I tend to put units that are "going away" in the far end of a prov and units that are going "home" in the nearest location.

BTW, thanks for the C, X and Z-tip. Maybee I should read the manual after all this time, he he!
