MRU is an acronym for 'Most Recently Used'. The column's MRU list contains the text of the items that were most recently selected by the end user.
When the property is set to true, as items are selected, a copy of the item is added to the top of the MRU portion of the list. The other items contained in the MRU list, if any, are moved down. This process continues until the number of items in the MRU portion exceeds the value specified by the property. When this happens, the 'oldest' item is removed from the list.
Note: While the MRUList can be set, items that do not match the text of an item in the columns's collection have no relevance and are discarded.
