Choosing Tools () gives you access to three actions.
Clicking this option will open a copy of the PDF background of your template.
Choosing this option will save a zip file version of your template that includes the PDF, field settings and related option lists. It is recommended that you export your template before you make a lot of changes. This can be used to keep multiple versions of your template in case you make a mistake and have to revert back.
Selecting this option will open a dialog with the source template filled. Enter a New Template Name and click on the Duplicate button.
The duplicated template will now be displayed in the Templates List.
