The Entry Settings Setup dialog box appears.
2. Select the script that you want to copy, and then click Copy Selected Navigation Script.
The copy appears in the Perio Navigation Scripts list and is named Copy of [name of selected script].
3. To edit the script that you copied, select it, and then click Edit.
