There are various ways to refine a selection set in ArcMap. You can add to a selection set or you can remove records from it. Either way is a means for honing in on a specific set of records for analysis. It is sometimes easier to refine a selection set in the Show Selected Records view of the table where you can work with selected and highlighted records.
- In the Table window, click Show Selected Records .
- In the Show Selected Records view, right-click a record and click Unselect to remove that record from the selection.
- To remove the highlighted records (those displayed in yellow, by default), right-click and click Unselect Highlighted , or press BACKSPACE.
- To select only the highlighted records and deselect all the other records, right-click and click Reselect Highlighted .
Reselect Highlighted enables you to refine the selected set by limiting it to the records you have highlighted.
