You can sort Data Sets by clicking on a column heading in the Available Data Sets list.
Once a column heading is clicked, the Data Sets are sorted in ascending order (i.e., 1-100, A-Z) for the Keyword Value in the column. To display the Data Sets in descending order (i.e., 100-1, Z-A), click the column heading a second time.
Once the Data Sets are sorted, you can find a specific Data Set by typing a few characters of the Keyword Value that is displayed in the first column in the Selected Data Set window.
