Formations and holding them

[Nerdymidgetkid]

I've seen in youtube vids that when sending in a unit, you can see where all the other units are going to. Also that you can hold the exact formation they're in when you have arrayed them all nicely and want to march in that formation to meet the enemy. How do you do these things?

Holding the space key while the units are selected will show where they will go.
Group the units when put in formation. Select group. Move group.

Peasant phill has the answer. Use control+number to make a group. You can also hold right mouse button to manipulate troup formations.
