Switching the selected set in a table

There are various ways to select features in ArcMap. One way is to select features through an attribute table. From a table, you can interactively select records by pointing at them, or you can select those records that meet some criteria, for example, find all cities with a population greater than one million.

When you create a selection set from a query, you will often want to analyze the records that were not selected (that did not meet your criteria). The ability to switch the selection allows you to easily work with two sets of records that differ from each other.

  1. Right-click the table or layer in the table of contents and choose Open Attribute Table.
  2. Click Table Options in the table and click Switch Selection Switch Selection.

    Optionally, use the keyboard shortcut CTRL+U to switch the selection.


Switching the selection in a table, especially for large datasets, can cause performance to slow while the selection is being executed.
