You can edit project content while you are in the preview panel without having to return to the edit view of your application.
Follow these steps to edit your content:
Check the toolbar and verify that you are working in the correct project.
In the Rules section of the navigation tree, right-click the rule that you want to preview.
If the rule that you are previewing appears on more than one page, a selection dialog appears. Select a page that you want to preview.
The information about the previewed page appears in the manifest. If the layout of the page is not quite what you expect, note that hotspot mode includes extra padding between some components. Try turning off hotspot mode by clicking the Hotspots checkbox.
During your preview session, if you want to return to the place where you started in the Rules navigation, click Keep Editing.
Hover the mouse over the menu (the gear icon) in the section of the preview application that you want to edit and click Edit.
Alternatively, in the manifest you can right-click the item you want to edit and click Edit.
Once you have finished editing your project, click Save.
Any changes that you made are reflected in the preview application.
Once you have finished editing, click Save and Preview to see your changes.
If you are not satisfied with the results, click Keep Editing to make more changes.
If you need to see the navigation tree that displays along the left side of Experience Manager while you edit, hover the mouse over the menu in the section of the preview that you want to edit and click Show in tree.
