Tools - Selection Conditions - Replace with Selected Cases

From the Tools - Selection Conditions submenu, select Replace with Selected Cases (or click the toolbar button located on the Tools toolbar) to add the selected cases in the spreadsheet to the Include cases group box on the Spreadsheet Case Selection Conditions dialog, replacing all other selection conditions. Hence, new selection conditions are created that include only the selected cases. To view the updated case selection conditions, select Tools - Selection Conditions - Edit.
