Walkthroughs and Tooltip Topic types have an option to see the topic in Flow view. It is accessible in the Authoring tool after you open a Topic. The Flow view is located in the top part of the Authoring tool right under the Topic title and ID.
After opening the Flow view you will see the Flow chart which gives you a graphical representation of your Topic. You will see arrows showing you where the user will be taken based on the conditions you defined.
There are no edits you can do in this view, it is only for viewing purposes.
