To delete an object type, select it in the table and the click the Delete button.
To delete several object types, select them by clicking on them while holding down the control key, and then click the Delete button.
To delete all the object types, click the Delete All button.
To move object types using the keyboard, select them and type Ctrl-X. Use the arrow keys to move to the required position and then type Ctrl-V.
If you are moving more than one object type, the object types must be next to each other in the table.
