Annotation Mask Behind

Masks behind the annotation of a selection set of annotation objects (Attdef, Dimension, Attribute, Mtext, Text, or Tolerance), using one of several masking methods (2dSolid, 3dFace, Trim, Wipeout, and ToolPac's MaskImg).

Keyboard Command: AnnMskAdd

If the routine determines that your AutoCAD configuration supports the Wipeout object, it will show as an option on the list. The buffer offset distance is the extra space to provide around the annotation object.
