When you edit in command-first mode, you have all the selection options described in the previous section — single object, window box, window polygon, crossing polygon, and crossing box — plus a slew of others. If you type ? and press Enter at any Select objects prompt, AutoCAD lists all the selection options at the command line:
Window/Last/Crossing/BOX/ALL/Fence/WPolygon/CPolygon/ Group/Add/Remove/Multiple/Previous/Undo/AUto/ SIngle/SUbobject/Object
Table 10-1 summarizes the most useful command-first selection options.
|Window||All objects completely within a rectangular area that you specify by picking two points|
|Crossing||All objects within or crossing a rectangular area that you specify by picking two points|
|WPolygon||All objects completely within a polygonal area whose corners you specify by picking points|
|CPolygon||All objects within or crossing a polygonal area whose corners you specify by picking points|
|Fence||All objects touching an imaginary polyline whose vertices you specify by picking points|
|Last||The last object you drew (whether or not it's visible in the display)|
|Previous||The previous selection set that you specified|
|ALL||All objects on layers that aren't frozen or locked and that are in the current space (model space or paper space)|
