Last Selects the most recently created visible object. The object must be in
the current space, that is, model space or paper space, and its layer must not
be set to frozen or off.
Crossing Selects objects within and crossing an area defined by two points.
A crossing selection is displayed as dashed or otherwise highlighted to
differentiate it from window selection.
Box Selects all objects inside or crossing a rectangle specified by two points.
If the rectangle's points are specified from right to left, Box is equivalent to
Crossing. Otherwise, Box is equivalent to Window.
All Selects all objects in either model space or the current layout, except those
objects on frozen or on locked layers.
Fence Selects all objects crossing a selection fence. The Fence method is similar
to CPolygon except that that the fence is not closed, and a fence can cross
itself. Fence is not affected by the PICKADD system variable.
