Help Viewer Contents tab page
The Contents tab page of the Help Viewer displays a list of predefined bookmarks to some Application Help pages.
The Contents list is not meant to be a complete inventory of all guide pages (How-to topics). It was created as a quick intro to the pages that might be most important. However, once we have a defined consecutive order of guide files, we may derive a new tree file set from that list.
The list is maintained manually by Application Help authors. In an installed help you can find the definition files with an extension of .tree. In the helpcontent2 module, they are in source/auxiliary. The translated files must be present in their subfolders. It is important that every link written in the .tree file must also exist as a file, else the OOo build will not succeed.
