some ssget  like "_W" need other infromation to work. in this case it needs two points Lower left and upper right of a rectangle.

 

(ssget "_W" '(3 2) '(5 4))

 

This will select anything that is 100% inside the rectangle that goes from (3,2) to (5,4)

 

More here or here

 

--Edit

(ssget "_X") - is selecting everything in the drawing and doesn't need points.

(ssget) - is waiting for you to make a selection by default
