Arguments

target	A reference to a buffer or select list from which with the contents of source should be deleted. A reference must begin with a %, !, &, or # character, followed by a number (%2), or followed by another of the four reference characters (%%).
source	The text to be deleted from the target buffer or select list. Can be a literal or a reference to a buffer or select list.
