box-comment-out-selection in scheme:text<%>

This method comments out a selection in the text by putting it into a comment box.

• (send a-scheme:text box-comment-out-selection start-pos end-pos) -> void
     start-pos = 'start : (union 'start exact-integer)
     end-pos = 'end : (union 'end exact-integer)

  Removes the region from start-pos to end-pos from the editor and inserts a comment box with that region of text inserted into the box.

  If start-pos is 'start, the starting point of the selection is used. If end-pos is 'end, the ending point of the selection is used.
