New domains are created by selecting Insert > Domain or clicking the Domains   icon. Note that creation of domains from the menu bar or toolbar may subsequently require selection of the appropriate analysis type. Domains can also be created by right-clicking the appropriate analysis type in the Outline tree view.

Creating a new domain will present a dialog box where a unique name for the domain should be entered.

Additional information on valid names is available in Valid Syntax for Named Objects. Existing domains may be edited by double-clicking the domain in the Outline tree view, or by right-clicking the domain and selecting Edit. For details, see Outline Tree View.
