The event items which appear in the History Log and To Do list when you add an entry, are known as System Events.
New System Events can be added in the User Defaults. These can be accessed by those who have the correct permissions.
- Click Defaults on the main toolbar
- Click User Defaults on the dropdown menu
- The Standard tab will be displayed. In System Events on the lower left column, an additional System Event can be added
- Overtype the displayed entry with the name of your new System Event
- On your keyboard, press the Return key
- Click Yes to confirm to add the new System Event or No to cancel
- Click Close
The new entry will now show in the dropdown options when you add a new To Do or History Log entry.
