Rename a Coggle Diagram
The title of a Coggle diagram is always the same as the text in the central item – so to edit the title, or change the name of a diagram, just open the diagram and click the central item to edit it. It’s as simple as that!
If you need a subtitle, or more content in the central box, then you can add multiple lines: use [ctrl]+[enter] to start a new line, or drag the corner of the editing area downwards.
