Report Editor: Open AutoStyle dialog box

Use the Available AutoStyles boxes to navigate to the directory where your autostyles are saved. When you select an autostyle, the Preview area changes to reflect what your report will look like if you apply the selected autostyle to it.

You can use the check box to Copy this AutoStyle into 'My Objects' folder, which allows the selected autostyle to appear in the Autostyles drop-down list on reports.
