The 
(Compare) function compares the data in the Project To Do List with the data in the target. This is valuable when more than one person is working
on the source or target, as the Project To Do List is a snapshot of the situation of the target when you copied the source items to
the Project To Do List. If a change is made to the target, between you adding items to the Project To Do
List and the copying of the items to the target, then the status of the Project To
Do List items may change but the changes are not reflected in the display. Selecting
compares the status between the Project To Do List and the target and creates a new snapshot of the Project To Do List changing the status icons where necessary.
