Column & Echelon movement

[Reddog]

Had some spare time and was thumbing through the EIF Players Guide and came across a few commands that I've never used. I was wondering if there are any players that have used either or both of the "Column & Echelon" movements during battle?

If so where and how do you use it or maybe a better way to ask is do you find it useful? Are these tools mostly used during large scenarios say divisional size infantry advancing while you're commanding an Army or Corp size game?

What are your thoughts?

An off topic question:

Does anyone know if there is a "Hot Key" for "Displaying Fixed Units"?
