Code names of automatically used alternative forms

If you create an alternative form and give it one of the reserved code names listed below, the system automatically uses the alternative form when performing the corresponding action.

For example, if you create an alternative form for a page type and give it the insert code name, the form is used when pages of the type are created in the Pages application.

The following table shows the reserved code names and the actions for which the particular forms are used:
