Selected Objects Pane 

The Selected Objects pane (top-right pane) contains the set of objects that have been linked to the current record. Unlink objects from the current record by highlighting one or more objects from this pane and moving them to the Available Objects pane.

A count of the number of selected objects appears in square brackets ([]) next to the static text that labels the pane.

The same object selector dialog is used for both single-valued and multi-valued object lookup fields, as indicated by the title bar of the dialog. A single-valued field will open the Select Single Object dialog and permit you to move only a single object to the selected list; a multi-valued field will open the Select Multiple Objects dialog and permit you to move multiple objects.
