Name of the custom unit

You can save the defined unit for a later use. By this way you can have a collection of the custom units, from which you can select in the corresponding ruler submenu. To save (and further select) a custom unit you should name it with some descriptive text. Type the name of the unit in the Name box, then use the Save button to permanently save the custom unit under this name. The adjacent drop-down box contains list of all already saved custom units, so it can be used to select such unit for editing. The Load button fills the dialog with values of the saved unit whose name appears in the Name box. Use the Delete button to permanently remove a custom unit from the saved collection, or use the Delete All button to delete all saved custom units.
