• Save & Publish: This would mean the author has completed the loading of content and the Topic/Chapter is now ready to be published. 

• Save as Draft: This would mean the author is still working on content and the Topic/Chapter is still in progress.

• Preview - To preview the final look of the online content before it gets published. 

• Cancel - To Cancel the Process. 

You can simply click on Save as Draft If you are not ready to publish it.
