Edit bar controls: Command, Add, Subtract, Retain, Show drag handles, Move entities, Group select always, Leave original
This tool allows you to select entities in the same way that Select Box does, but then you can use drag handles to move or stretch the selected entities.
You can pick directly on a single entity. Alternatively if you pick away from any entities, this is taken to be one corner of the rectangular area and you should then pick the opposite corner of the area. All entities totally or partially within the area will be selected. If the Group select always 
option is switched on then you will always need to specify a rectangular box.
When defining the rectangular area, if you pick a left corner first, then move the cursor rightwards, you will select all entities which are fully or partially within the rectangle. Alternatively, if you pick a right corner and move leftwards, you will select only those entities which are fully in the rectangle.
You can modify the operation of this and most other selection tools with the Shift and Control keyboard keys - please see Selecting Entities for more information.
You can also make use of saved Select Expressions via the Command 
, Add 
, Subtract 
and Retain 
edit bar controls.
If you want to edit the selected entities you should have the Show drag handles 
option switched on. A description of the Move entities and Leave original options is given on the Drag Handles page.
Nudging
You can use the Left, Right, Up and Down cursor keys to move the selected entities in the appropriate direction. Using the Shift and Control keys you can also modify the distance to move them. The distances are configured in Snap Settings - Nudging.
