The Actions page lets you use the Form Action Properties dialog box to define how the form responds to user actions. By setting the options presented here, you need not write script to support those actions. After you make settings on the Actions page, those settings are reflected (optionally) on the menu and on the toolbar.
The tab to display the Actions page is visible in the illustrations of the forms in the topics Illustration of the IPM.Post.EnhancedLitCrit Form and Illustration of the IPM.Post.ToApprover Form.
