SE 2D work on autocad .dwg

I have opened one of my autocad .dwg electrical schematic drawings in SE 2D. I cannot find a move comand and several commands I an used to using for drawing modification. will I be able to copy/move an entire drawing as a block so parts can be copied as i do in autocad?
I read that there is a tutorial for autocad users to convert to SE 2D accessable under help. I cannot find it. After modifications should I be able to open the drawing in auto cad? Is there a tutorial on SE 2D from autocad? Is there a chart to understand the non verbal names for various functions? Will I get answers on this by email, or do I have to find my way back here?
