A list of different options available for the application will be listed here along with the type and value. To remove an option select the "delete" button and to change the value of an option select the "edit" button, make the necessary changes, and then select "Save".
Adding a brand-new option
Select Add New Option to create a key that doesn't exist yet. Enter the Option Key, pick a Value Type (Boolean, Short Text, Long Text, Long, or Double), enter an Initial Value, then select Create. If a key with the same name already exists, the create is rejected — edit the existing row instead.

The "Add New Option" dialog — creates a genuinely new key rather than editing an existing one.
