In the comment below, the first word is a description of the annotation property that is changed. If there is a reference to an LAnnXXXX function, see the documentation of the function for a complete description of the property.
Please note that formerly ANNCHANGE_DELETE had the value [0] and ANNCHANGE_ROTATE had the value [93].
