In any Workspace App or Settings, new items are simple to create.
From the menu, first select File and then New.
If items already exist, there is a shortcut available. Just make sure an item in the Table or List (depending on the View selected) is highlighted, then press the "N" key.
Enter a Name for the new item, and add values to any available fields.
After completing the necessary fields, click the Save icon. New items will be saved at the end of list of items.
