Title and Description
The title should shortly describe the purpose so that an addressee already recognizes your concern in the list view.
If you press the key combination "Ctrl-Space" the titles you have already created are displayed that match with the letters you have just entered.
Under "Description" you can edit the detailed information needed by the processor to accomplish the job.
Use the formatting features to structure the description eg by lists and tables. Add a photo if it is useful for the Todo.
