“Move” command.

The command moves as the name suggests is to move one or more objects from one point to another of the drawing.
It is activated by clicking on this icon  which is on the "modify" toolbar.
At this point the crosshair cursor changes to a selection handle and the "command line" is written to "select objects".
You must now select one or more objects to move and you can do so by clicking on each one individually or by selecting one or more windows, then we need to confirm your selection by pressing Enter or the right mouse button.

Please note before pressing enter, you can remove items from the selection made by holding down the "shift" key on the keyboard and simultaneously selecting new, individually or with a selection window.

This is a general concept to remember, regardless of use by various commands in Autocad, you select objects by clicking on it and clear it again by clicking while holding down the "shift" , or by pressing "esc" you clear all.
The selected objects change their appearance becoming slightly dashed.

Once you have selected and confirmed the items to be moved Autocad asks us to establish two points, clicking with the mouse:
- The starting point against which to move objects.
- The destination point where we're going to put things, relatively to the first point selected.

This means that if you move such as a square, you can select as a first point of displacement, an angle (using the snap), or even a point outside the object, is the vertex of another object that a random point on drawing area.

I hope you understand this concept well and I get a picture to help you:

Well, if you want to move the blue square below the red maintaining the distance ( A ) between them, you can select as the first move point a corner of the green square and the same angle as the second point on the red square.

If you want to attack the blue square below the red will be chosen as a first point one of the two vertices on the top of blue square and a second point one of the two vertices in the bottom of the red square.

Summary:

1. Activating the command moves 
2. Selecting objects to move
3. Confirm selection by pressing Enter or the right mouse button
4. Select the first point of reference
5. Select the second point of destination and exit the command.
