Re: Battle-field waypoints
The last "shift-click" will be your final destination, you can see after you've finished issuing orders by pressing the space bar, that will indicate where your troops will end up and which way they face.
You can make them run by "shift-double-click" and it should remember from and to which way point you want them to run (they don't have to run every section of the maneuver).
You can also use shift to draw out the formation as well, say for example the first way point you want your troops to march north but at the second way point you want them to turn and face south. Just use shift and right click to draw out precise formations and moves.
Sorry not the best at explaining things but i gave it my best shot, hope that helps! ~;)
